ABOUT ME

My name is Gabriel Gonzales and I am a graduate from New Mexico State Universitywhere I successfully obtained my B.S. in Mechanical Engineering Technology. I’ve had several beneficial internships and part-time jobs throughout college and have continued to develop after graduating. My experiences have allowed me to excel in Research & Development, Product Design, and Testing in various fields. I am seeking to continue my development and add value to a team by obtaining a full-time position in a Product Development role. I’m striving to leverage my education and experience in Design, Research & Development, Process Development, Package Development, all while adding value to a team.

Shell & Tube Boiler/Condenser

• For my Capstone Project, myself and two other group members were given the task of building, testing, and determining the feasibility of a Multi-Stage Desalination Vacuum Still to purify water.

• Using concepts in Patent No. 8282791, which outlines the details and concept of a naturally maintained desalination process, our group designed and simulated various designs using Solid Works to determine which would best meet our goals.

Shell & Tube Boiler/Condenser • Each stage increasing in height, allows for an increase in vacuum within that

stage due to increased barometric head caused by a syphon.

Multi-Stage Desalination System

• The increase of vacuum within each stage allows for a decrease in the vapor pressure of the liquid in each stage, thus decreasing the boiling point of that liquid.

• The steam put off by each stage would condense by the rejection of heat to the following stage. This rejection of heat would then cause the liquid in the following stage to boil.

• The condensed liquid from each stage would be collected as the distilled liquid.

5

Shell & Tube Boiler/Condenser • Solid Works was used to design and

perform flow simulations in order to determine the appropriate surface area of the condenser for a target flow rate.

• Our Capstone team developed several iterations before we achieved a design that met all our specifications.

6

Shell & Tube Boiler/Condenser

• Fabrication of the prototype moved smoothly utilizing the Detailed Drawings and Bill of Materials I created in the design process.

• Some modification of purchased materials and fittings allowed us to cut costs and fabrication time.

First stage: Shell & Tube Boiler/Condenser

Three Stage Condensing and Pre-Heating Unit 7

Shell & Tube Boiler/Condenser • I performed preliminary tests with a

single stage to prove that our calculations and design would perform as intended.

• Pulling a vacuum and using warm water from a sink as a heat source, we successfully boiled water!

8

Shell & Tube Boiler/Condenser

• I took it upon myself to exceed expectations and designed, as well as built an adjustable stand that allowed for easy transportation of the unit for presentation purposes.

• As seen in the pictures, the design utilized an adjustable mast to allow for proper height difference to achieve appropriate vacuum.

Procter & Gamble

• For my summer internship at Procter & Gamble, I was given the task to develop a new Variable based test method for determining Blistercard Seal Integrity.

• The Blistercard Seal Integrity test method being used was an Attribute based test which did not provide enough granularity to fully understand the seal qualities of blister packaging.

• Furthermore, an Attribute based test requires a large test size, which means a large loss of product occurs.

Blister Packaging-Test Development

10

Package Test Development • In developing a Variable based test, I leveraged technical curiosity to determine areas of

improvement and implementation of current tests based off of ASTM test standards.• Once an alternative method was agreed upon, I validated the process through design of

experiments (DOE) and statistical analysis of the test data.• The overall outcome of my efforts was the development of a statistical model that was

able to determine and predict failure percentages based off of various seal qualities.• At the end of my Internship, I made recommendations on how to incorporate the

alternative test method based off of final results.• Alternative test method reduced test size, costs, and allowed a better understanding of

seal qualities.

• Sapphire Energy is a Green Energy company that produces crude oil from algae.• My role was being part of the Harvest Process Development Team.• One of my greatest achievements while at Sapphire Energy was implementing

modifications to the current harvest process, which used Dissolved Air Floatation(DAF) technology .

Harvest Process Development

12

No Micro Bubbles are seen in the Chamber.

• DAF is a process used for clarifying a liquid by the injection of micro bubbles that bond to solids and bring them to the surface for removal.

• The method being used to inject the dissolved air was not efficient as air was settling out of the solution before reaching the main chamber, thus decreasing harvest efficiencies.

Harvest Process Development

13

Harvest Process Development • After evaluation, it was determined that the location of injection and the method

of maintaining pressure was the cause of the absence of dissolved air in the main chamber.

Injection Points into the inlet Manifold

14

• New injection points were created to inject directly into the the chamber.• Also, I determined that maintaining pressure at the injection points prevented

air from settling out of the solution.

Injection points with valves maintaining desired pressure.

Harvest Process Development

15

• After testing and evaluation, saturation of air throughout the chamber was achieved.

• Thus increasing the efficiency and overall performance.– Efficiencies increased to an average of 90%

Complete saturation achieved!

Kinematics-Reverse Engineering• One of the projects assigned

in my Kinematics course was to reverse engineer a basic kinematic machine as seen here.

Crank Slider

17

• The outcome of my efforts was an interchangeable crank and slider mechanism as seen here.

• Measurement points were incorporated into the design in order to be able to measure angular and linear displacement, velocity, and acceleration.

• Interchangeable links were also designed to compare the effects of using straight, angled, or curved links.

• My design was one of the three selected from the class to be printed on NMSU’s 3D Printer.

Kinematics-Reverse Engineering

• General layouts, as seen here, are created for the use of contractors. General layouts highlight specific details of the generator that require attention from the contractor, such as electrical stub-up areas and pad layouts.

• Custom equipment is also shown in the general layouts to aid in the Up-Fit of the unit.

• I will take it upon myself to add detailed wire-runs to allow for the contractor to determine what conduits will need to be installed for a clean install that will meet code.

Details such as stairs with platforms and Load-Bank CamLoks are shown in Genaral Layouts.

• Seen in the picture above, I equipped an Electronic Fuel Level Sensor on a factory tank to meet the customers needs. I modeled the system in order to determine the most effective use of the space provided.

• Detailed labeling and notes eases the fabrication and installation process for the Up-Fit Technicians. 20

• I took it upon myself to create a calculator; using Excel, that aids in the configuration of the Electronic Fuel Level Sensor (as seen on page 20) for ordering purposes.

• I also included a Fuel Level Calculator that allows for the technicians to accurately calibrate the Electronic Fuel Level Sensor, after being installed in the fuel tank. 21
