Dear Readers,

Electricity-based processing methods are not new to chemical engineering. Shell

worked on an induction-heated cracking unit in early 1950s. Microwaves or ultra-

sound in chemical reactions have been investigated for at least 30 years. Meanwhile,

some electricity-based techniques have found their paths to industrial applications.

Examples are electric-field based coalescers or electrothermic oil recovery process.

Many of those techniques, however, still wait for a convincing business case and the

most important hindering factor is the current electricity price. Conventional, steam

boiler-based heating is simply cheaper.

On the other hand numerous serious institutions, such as NREL of International

Energy Agency predict a substantial growth of the renewables-based electricity in

the coming decennia. According to NREL in 2050 about 80% of the US electricity

will come from renewables. The price of solar or wind energy will decrease by fac-

tors and this trend is visible already now.

The question therefore is whether we should intensify the research of novel chemi-

cal processes, which, instead of combusting fossil fuels and generating CO2, will be

using green electricity as primary energy source. My personal opinion is: absolutely

yes!

ExxonMobil in their latest report The Outlook for Energy: A View to 2040 wrote:

“Thomas Edison probably could not have envisioned all the ways people would use

electricity in the 21st century”. I sincerely hope that the chemical process industry

will become one of these ways.

Another, more local electrifying news of this year is that with coming of Johan

Padding with his team of postdocs and PhDs the IRS Group has regained its original

shape. Johan and his co-workers have brought with them many new projects and

new ideas that will surely enrich our research

portfolio in the coming years. Welcome on board,

guys!

Season Greetings to everyone!

In September 2016 I moved with my team of 3 PhD students and 2 postdocs from Eindhoven to Delft Uni-

versity of Technology. Let me first introduce the ERC project we are working on, and then give a short

biography of each of the team members.

ERC project on gas-solid flows of non-spherical particles

In various industrial applications, solid particles are transported and processed in gas flows. To design

and optimize the processing equipment it is important to have available accurate predictive simulation

models for the flow (hydrodynamics) and heat and mass transfer processes. Unfortunately, existing sim-

ulations models have been developed for spherical particles, while particles are often non-spherical.

-spherical particles experience anisotropic drag and lift forces, and have complex direct interactions

which lead to mutually ordered configurations at higher volume fractions. An important example is the

gasification of milled biomass particles in fluidized bed reactors, where the particles are fibrous and al-

most rodlike. In our ERC Consolidator project we are developing new models for gas-solid flows with

rodlike particles at three interconnected levels (in between brackets the main PhD students or postdocs):

1. On the lowest level we apply Direct Numerical Simulations (DNS), in particular using Lattice Boltz-

mann simulations, to find correlations for the fluid-induced drag, lift and torque on collections of

rodlike particles (Sathish Sanjeevi, Ahad Zarghami).

2. On the intermediate level we develop new Discrete Particle Models (DPM), which use the correlations

from DNS to handle larger numbers of particles. These models are validated against lab-scale fluid-

ized bed setups, where we measure the hydrodynamics using Particle Image Velocimetry and Mag-

netic Particle Tracking. After validation, these models are used to find correlations for the particle-

phase stress as a function of deformation rate and mutual alignment of the particles (Vinay Mahajan,

Ivan Mema, Barry Fitzgerald).

3. On the highest level we develop new coarse-grained multi-particle collision (MPC) models, in which

the particle-particle collisions are treated implicitly through the stress correlations obtained from the

DPM simulations. The goal is to be able to model industrial scale fluidized beds containing rodlike

particles (Vikrant, Barry Fitzgerald).

As you can imagine, this work requires intense collaboration between physicists, chemical engineers and

mechanical engineers, all of which are present within the ERC team. Now each of the members will intro-

duce himself.

Johan Padding I received my MSc (summa cum laude) in Applied Physics from the University of

Twente in 1998, and my PhD (summa cum laude) in Chemical Physics from the

same university in 2003 on the topic of modelling the dynamics and viscoelasticity

of polymer melts. The following 3 years I was a Postdoctoral researcher at Univer-

sity of Cambridge (England) working on the dynamics and sedimentation of colloi-

dal suspensions, and visiting researcher at Schlumberger Cambridge Research (an

oilfield technology research company) working on the rheology of viscoelastic

wormlike micellar surfactants. Then I received a VENI scholarship to work 3 more years on fiber suspen-

sions at University of Twente. After another 2 year postdoc in the field of pressure-sensitive adhesives (the

glue on your Post-It!), I started as an assistant (later associate) professor in the Multiphase Reactors (SMR)

group at Eindhoven University of Technology. Here I extended my research to modelling and experiments

on fluidized beds, granular flows, spray dryers, and viscoelastic flows through porous media. I have also

guided several PPD (process & product design) students in their industrial internships related to e.g.

reactor modelling and crystallization.

In summary, my interests are quite diverse but my passion is always to understand complex flows, wheth-

er the complexity arises from the microscopic structure of the fluid (polymers, colloids and other soft mat-

ter), the confining geometry (microfluidics, porous media), or the multiphase character (liquid sprays, gas-

solid flows). I am looking forward to learning lots more by interacting with all of you within IRS and the

rest of the P&E department.

P.S. I am married and have two sons, Finn (11 years old) and Lars (7 years old). In my free time I enjoy

travelling, photography and butterflies, and combining the three.

Sathish Krishnan Sanjeevi I come from Chennai, a city located in the southern part of India. I did my

Bachelors in Mechanical Engineering from Amrita University, India and after

my graduation, I worked for Larsen & Toubro Power as a power-plant engi-

neer for 2 years. Later, I did my MSc in Simulation Sciences jointly

offered by RWTH Aachen University and Juelich supercomputing center in

Germany. After my Masters in 2014, I started my PhD with Johan Padding

and Hans Kuipers at TU Eindhoven, and recently moved to TU Delft with Jo-

han. In my free time, I like cooking, cycling, running and traveling .

Ahad Zarghami I completed a PhD in Fluid Mechanics at Shahrood University of Technology,

Iran. After finishing my PhD, I joined the La Sapienza University of Rome as a

researcher for one year. After that, from April 2014 to April 2016 I was a post-

doc in transport phenomena group of the department of Chemical Engineering

at TU Delft. In April 2016, I started my second post-doc career in the SMR

group at TU Eindhoven and finally from September 2016, I joined the IRS

group of the department of process and energy. My research focuses on the

application of mesoscopic numerical techniques for modeling of complex fluid

flows such as particle-based flows, multiphase and free surface flows and fluid

flow in porous media.

Vinay Mahajan I did Bachelors in Chemical Engineering (2010) from National Institute of

Technology, Rourkela, India. Later, I worked in National Chemical Laborato-

ry, Pune for two years as a researcher before moving to Netherlands for

Masters in Process Engineering (2014) at Technical University, Eindhoven.

From November 2014, I started my PhD on Johans ERC project in SMR

group, TU/e. I am still based in Eindhoven and performing experiments at

TU/e, therefore most of you haven’t seen me often yet. I come from Nagpur,

a city located in central India. I love traveling and like playing squash, table

tennis and FIFA.

Ivan Mema I have finished my Bachelor and Master studies in Chemical Engineering at Faculty of

Technology and Metallurgy in Belgrade, Serbia. Du ring my studies I had an intern-

ship at Universidade Estadual de Campinas (Unicamp) in Capminas, Brazil, where I

worked on study of heterogeneous catalytic reactions. After my master studies I

worked for two years as process and development engineer in explosives factory

“Prva Iskra – Namenska a.d.” in Belgrade. From December 2015 I joined the SMR

group at TU/e as PhD student under Johan Padding. In September 2016 I moved to-

gether with Johan and rest of ERC team to TU Delft, IRS group of department of pro-

cess and energy. I work on the intermediate level of the ERC project, where I develop a DPM model for non-

spherical particles with a focus on bulk behavior and validation with noninvasive experimental techniques.

Barry Fitzgerald I completed by Bachelors degree in Applied Physics (1st class honours) at the Uni-

versity of Limerick (UL), Ireland and in 2010 I received a PhD in Computational

Physics from the same university. After my PhD I worked as a Scientific Projects Of-

ficer in Teaching and Learning at UL. In 2012 I moved to the Netherlands to work as

a postdoc in the group of Wim Briels (Computational Biophysics group) at the Uni-

versity of Twente. My work there was focused on the simulation of polymeric sys-

tems. In October 2014, I moved to TU Eindhoven (TU/e) to work on lattice gas mod-

els of complex fluid flows with Rutger van Santen and Johan Padding at the Institute

for Complex Molecular Systems (ICMS). In October 2015 I then started my position as a postdoc researcher

with Johan and the ERC team in the SMR group at TU/e and subsequently moved to TU Delft in September

2016 along with the ERC team. My research interests include fluidised beds, granular flows, complex fluid

flows, polymeric systems, complexity, collective motion in active systems and science education. I come

from Limerick, a city in the west of Ireland built on the river Shannon. In my spare time I run the occasional

marathon, play guitar, watch films and attend FC Twente Enschede games at de Grolsch Veste. I also write

popular science books and in 2016 I self-published two books – “Secrets of Superhero Science” and “Secret

Science of Santa Claus”.

Vikrant I received my Bachelor in Chemical Engineering and Master in Computer applications

in Chemical Engineering from Indian Institute of Technology, Delhi, India. In 2014, I

received my PhD from Eindhoven University of Technology, The Netherlands in the

group of Prof. J.A.M Kuipers. During my PhD, I developed kinetic theory based two-

fluid model to study gas-solid fluidized beds. I performed experiments on a 3D fluid-

ized bed using ultrafast X-ray tomography, and used it for validating computational

models. After my PhD, I spent two years as a postdoc in the multiphase flow science division at National

Energy Technology Laboratory, USA. There I worked on development of open source MFiX code, that in-

cludes (1) computational modeling of complex geometries using cut-cell method, (2) development of sub-

grid gas-solid drag for vertical tubes in fluidized beds, (3) CFD-DEM, and coarse-grained DEM simulations

of particle segregation in rotating fluidized beds in vortex chambers, and (4) application of CFD-MFiX code

for carbon capture using solid sorbent in fluidized beds. From January 2017, I will be joining the IRS group

as a postdoc on coarse-grained modeling of fluidized beds with non-spherical particles.

Marloes Anne Reus was born on the 7th of September 1984 in Heiloo (the Netherlands). In 2010 she

obtained the Master of Science degree in Chemical Engineering from Delft University of Technology

and stayed there to pursue her doctoral research at the IRS Group under the supervision of Joop ter

Horst and Antoine van der Heijden. The research was done in cooperation with TNO Defence, Safety

and Security, where part of the work took place.

Her PhD research focused on using crystallization and microencapsulation processes to produce mul-

ticomponent particulate products with different functionalities (improved stability, controlled release,

protection from environment, etc.). Many products from chemical industries, such as consumer prod-

ucts, pharmaceuticals, food products and fine chemicals industries constitute particulate products.

The functionality of these products depends among others on the properties of its constituents, their

interactions and their distribution in the product.

Additionally, she addressed interactions between the components in the processes. In this context, she

investigated the crystallization in multicomponent mixtures, such as co-crystallization and anti-

solvent crystallization. She employed electrospray crystallization as a technique for producing multi-

component (sub-)micron sized crystals. Additionally, wheat gluten were encapsulated in a matrix of

hydrogel by a dripping method to delay fibrilization in a novel meat analog production process and

atomic layer deposition was performed in a fluidized bed on various compounds to protect them from

moisture or reactive species in the environment. She used model compounds from various industrial

fields (e.g. food, pharmaceutical and energetic material industries) to illustrate the wide applicability

of the tested processes. On 18th of March 2016, Marloes successfully defended her PhD thesis and re-

ceived the last ever handwritten PhD diploma of TU Delft.

George Krintiras was born in Athens, Greece on 6th September 1985. He attended secondary and higher

school at Volos, Greece. He received his Bachelor of Engineering degree in Mechanical Engineering from

the University of Southern Denmark (SDU), Denmark in 2005. For his B.Eng. thesis he worked on CFD

modelling of the aerodynamic drag on a student formula racing car.

He completed his Master of Science from Delft University of Technology (TU Delft), the Netherlands in

2011, specializing in Sustainable Energy Technology (SET). For his M.Sc. thesis he worked on CFD mod-

elling of gas diffusion limitations in fuel cell (SOFC) anodes. During his studies he founded and chaired

the student association for SET master students.

He joined Delft University of Technology (TU Delft) as Ph.D. candidate in September 2010 in the Depart-

ment of Process and Energy (P&E) under the supervision of Prof. A.I. Stankiewicz and Prof. G.D. Stefan-

idis. His Ph.D. topic dealt with the development of a scalable process for the production of fibrous meat

replacers. He introduced and developed a pilot-scale process for the production meat replacers that em-

ulate beef meat. At the same time he was exposed to advanced research tools like light microscopy, SEM,

TEM, texture analysis, encapsulation and neutron refraction (SESANS). These techniques helped him

during his scientific research and led to a publication devoted to the use and significance of these tech-

niques for a food technologist. During his Ph.D. he worked for half a year for the Vegetarian Butcher (De

Vegetarische Slager) in Utrecht, the Netherlands to further develop and promote the Couette Cell for

industrial production of meat replacers. His latest interests and research activities were focused on the

development of 3D food printers for home cooking and for industrial production. This work led to the

development of the first 3D “meat” printer for the production of vegetable-based chicken breast.

On 3rd of March 2016, George successfully defended his PhD thesis at TU Delft. Currently, he is working at FeyeCon.

On 1st of November 2016 I started as a PhD student in the Chair of Intensified Re-

action and Separation Systems, P&E Department within the Faculty 3mE.

Education and experience

I was born in 1990 in Izmir, Turkey. I graduated Bioengineering in Ege University,

during undergraduate education I got training from Department of Chemical Engi-

neering at Abo Akademi in Finland as an exchange student. After I was awarded

the M.S. degree in Department of Biomedical Technologies at I zmir Katip Çelebi

University.

Research

My research interests center around bioengineering, plasma medicine, microbiology, cell culture, bio-

material, surface modification. My bachelor’s project was the production of Lovastatin that was ob-

tained by using microorganism with solid state fermentation. My master’s projects were the biofilm

formation and eradication on endotracheal tube surface via plasma treatment to prevent and block

ventilator associated pneumonia disease, and sterilization of implant materials by using plasma to

inactivate microorganisms. In IRS group, I will investigate the suppression of kidney stone crystalliza-

tion/aggregation with designer microstructured biomaterials.

Introduction Eric Safai

I am pursuing a research internship in the Process and Energy Technology track of the

3mE Department, through which I intend to continue toward a Master’s thesis. While

interning at TU Delft, I will be developing methodologies to generate completely biocom-

patible microparticles using stop flow lithography. This concept has applications ranging

from pharmaceutical identification to high-sensitivity biomolecular assays.

I was born March 27, 1992, in Mountain View, California. After graduating high school, I

moved to Boston for university. I earned my undergraduate degree’s in Chemical-

biological Engineering and Biology from Massachusetts Institute of Technology (MIT) in 2014. While in

school, I gained various research experiences focusing on the application of hydrogel technologies, ranging

from selective encapsulation and isolation of circulating tumor cells, generation of oxygen-carrying biomi-

metic microparticles, and explorations into new techniques for rapid hydrogel synthesis of biocompatible

polymers.

After graduation, I worked at the Ragon Institute of MGH, MIT, and Harvard - also in Boston - a conglomera-

tion of labs focused on the developing vaccines and preventative medicines against HIV. Specifically, my lab

addressed acute stage infection in mucosal tissues – intestines, lungs, and female reproductive organs. I

investigated immune cell responses to acute HIV infection in the small intestines as well as implementing

high-throughput methods to identify unique antibody producing cells to combat Cholera. I also had the op-

portunity to assist in an effort to combat antibiotic resistance through the use of next generation sequenc-

ing methods.

Introduction Rumen N. Georgiev

On 17th October I began my PhD studies in the Chair of Intensified Reaction and

Separation Systems, P&E Department within the Faculty 3mE. I am working

under dr. H. Burak Eral’s supervision and my promoter is prof. dr. Andrzej

Stankiewicz. The main focus of my research will be the investigation of hydro-

dynamic interactions between asymmetric particles in low Reynolds number

flows. These interactions can be tailored to assemble particles into larger crys-

tal-like structures, which hold promise for the fabrication of advanced materi-

als with controlled properties.

Experience and Expertise

I obtained my Bachelor’s degree in Chemistry from Sofia University, Bulgaria, after defending my de-

gree project entitled ‘Adsorption models for surfactants with complex head groups’ (2014). During

the project, I carried out a theoretical investigation of the parameters governing the process of surfac-

tant adsorption to the water|air interface. The main result of the work is the development of a geo-

metric model with which one of these parameter, the surfactant cross-section, can be calculated theo-

retically.

For my Master’s degree I moved to Utrecht University, the Netherlands, where I worked on the prob-

lem of genetic regulation modelling. In my Master’s thesis, ‘The Gaussian Genome’ (2016), I addressed

the problem of transcription factor binding to non-regulatory DNA, modelled as a 1D Langmuir lat-

tice. The effective energy defined in the work takes into account the statistical distribution of binding

energies the lattice exhibits and enables the direct comparison of in vivo and in vitro experiments.

I also worked as an intern at the Max-Planck-Institute for Intelligent Systems in Stuttgart, Germany

(2016), where I studied the motion of a dumbbell-shaped microparticle driven by a Hele-Shaw flow

via simulations. This work serves as basis for my current appointment at TU Delft’s P&E department.

Farewell to Žarko Olujić

At the end of 2016 the IRS Group will say the formal “farewell” to Z arko Olujic ,

our long-time colleague and one of the world’s leading experts in the field of dis-

tillation.

The academic career of Ž arko knows three distinctive phases: the first one, from

1969 to 1987, being employee of the University of Zagreb, climbing the academic

ladder from research and teaching assistant to full professor, including a two

years (1974-1976) research period as DAAD fellow at the University of Karlsruhe

in Germany, the second one, from June 1987 to the end of 2005, being employed as Associate Professor at

Delft University of Technology (TU Delft), and the third one, from 2006 to the end of 2016, a post retire-

ment period being independent scientific consultant and an external, part time Associate Professor and

member, on guest basis, of the IRS Group.

During eleven years of his postretirement period with IRS, Z arko, a Fellow of AIChE, has contributed to the

Group’s output as an author or co-author of 2 patents, 1 book, 3 chapters in an online encyclopaedia, 2

chapters in books, and 51 papers in international technical and scientific journals, as well as 27 papers in

proceedings of international conferences.

Being now at the age of 70, from January 2017 on Ž arko will con-

tinue to be academically active as a scientific consultant and

knowledge transfer specialist in separations technology field, com-

bining this in warmer months with fishing and sailing along his

homeland grounds on the eastern shores of the Adriatic sea.

That love for sailing and Z arko’s regular trips to America have been

symbolically expressed in our goodbye gift (photo). We hope that

long hours spent on constructing “Mayflower” will keep bringing

back good memories of the years spent at IRS.

Dear Old Friend, we wish you all good winds in sails for many years

to come!

IRS Day-out

IRS group organised its traditional day-out on Octo-

ber 24th. After having a short brainstorming session

to share/obtain new ideas in different research

areas: water purification, recycle of a pollutant, ni-

trogen fixation and microwave technology, we went

to De Kokkerie. There, we learned a lot about cook-

ing methods and some really delicious recipes/food

in a kind of cooking journey. All instructions were

really easy to follow. We also met the chef of the

restaurant. His passion is to teach cooking skills. He

shared his knowledge and gave us many little tips about how to make everything easier and yummy. We

learned how to make delicious foods like piccata goat cheese with olive tapenade, Greek filo pastry with

feta, red onion and olives, iberico meat slowly cooked with Spanish spicy potatoes and Tiramisu dessert. At

the end we sat around the table to enjoy the meals together. It was definitely a very good experience to

have food, that we ourselves made, at De Kokkerie.

Leslie van Leeuwen will join the spinning marathon (3 hours) for ‘Sporten voor Sophia’.

Our goal is: more air for children with disorders of the upper respiratory airways.

The Erasmus MC – Sophie Children’s Hospital takes care of chil-

dren with upper respiratory airway disorders for which they

need to be operated, so that they can breathe independently once

again. Sadly, the upper airway often remains too narrow or weak

for many of these children. This often severely inhibits their functioning in daily life.. Each breath re-

quires effort; day after day, year after year. A consequence is that they often cannot join their peers in

fun and games without becoming short of breath, and that they are often ill. This has to improve!

With research, the treatment will be improved, thereby avoiding lifelong breathlessness. If you want

The use of alternative energy forms and transfer mechanisms is one of the key approaches of process intensification. In recent years, significant amounts of research have been carried out in de-veloping chemical processing technologies enhanced by plasma, electric and magnetic fields, electromagnetic and ultra-sound waves and high gravity fields. Discussing the broad impact of alter-native energy transfer technologies on reactions, separations and materials synthesis, this book reports on recent breakthrough re-sults in various application areas. It provides a comprehensive overview of the current developments in the field. The book ena-bles industrialists, academics and postgraduates in alternative-energy based processing to see the potential of alternative energies for green chemistry and sustainability of chemical manufacturing.
