Preface

The decision of the International Union of Theoretical and Applied Mechanics (JUT AM) to

organize a Symposium on Microgravity Fluid Mechanics represents a milestone for this

young and promising field of science. This Symposium was proposed to the General

Assembly of IUTAM by the "Gesellschaft fur Angewandte Mathematik und Mechanik"

(GAMM). With this decision JUTAM has recognized the rapid development of

Microgravity Fluid Mechanics towards becoming a full member within the community of

Mechanical Sciences and Fluid Mechanics.

The intention of the Symposium was to review recent scientific research results in the field

of Fluid Mechanics under strongly reduced gravity conditions and to discuss the "state-of­

the-art" in this discipline. A thematical structure was provided to the large topic of the

IUTAM-Symposium by six invited lectures which reviewed the various aspects of interface

phenomena of fluids under isothermal conditions and Marangoni-effects, combustion

phenomena, physico-chemical processes and multiphase phenomena, fluid handling,

dynamics of convectional driven drops and bubbles, residual acceleration effects, non­

Newtonian fluid flow and aspects of solidification. These invited papers were supplemented

by 22 orally presented contributions and 29 papers presented as posters. In accordance with

the IUTAM-regulations, there was no general call for papers. The contributed papers were

selected by the Scientific Committee from extended abstracts. Unfortunately, it was not

possible to include all papers in the Symposium. Practically all considered contributions

could be accepted for publication in the proceedings. This is the merit of the members of

the Scientific Committee who preselected the contributions from about ninety based on the

submitted abstracts.

The Symposium brought together many scientists from allover the world who are active in

the field of Fluid Mechanics under strongly reduced gravity conditions. The conference had

quite an interdisciplinary character as scientits from various research fields as Fluid

Mechanics, Physico-Chemistry, Combustion, Rheology, Mathematics and Physics took

part. The papers submitted showed in general that there is a progress and an increasing

interest in the field of Microgravity Fluid Mechanics. Furthermore the Symposium has

shown that beside using short-term facilities (drop tower, parabolic flights), Microgravity

long-term experiments could only be the tip of an iceberg of Microgravity Science. It is

necessary to stimulate the use of mathematical and numerical methods, to use more short­

term flight possiblities for Microgravity experiments and to use "small-scale" experiments

under terrestrial conditions to get a wider basis and a precise comprehension of the

different and interesting Microgravity Fluid Mechanics phenomena.

VII

Always many people were involved in the preparation and running of the symposium. I

would like to thank the members of the Scientific Committee who at all stages during the

preparation of the conference, maintained a very close rapport. In addition to the members

of the Scientific committee I would like to thank especially Dr. A. Delgado (ZARM) and

Dipl.-Ing. R. Kroger (ZARM) for their large effort and help. Thanks is also given to Mrs.

B. Schuldt, Mrs. B. Hiller and Mr. A. Nordmann and other co-workers of ZARM. We are

much indebted for the financial support provided by the sponsors which made this

Symposium possible.

The ready and efficient cooperation of Herro von Hagen and the editorial staff of the

Springer-Verlag during the preparation for the printing of the Proceedings is especially

appreciated.

It is our hope that this book will stimulate further research efforts in this exciting field of

Fluid Mechanics.

Bremen, September 1991 Hans I. Rath

Introduction

I have accepted the invitation of Prof. Rath, Chairman of the Scientific of Committee of

this Symposium, to address some introductory words on this Symposium with great

personal pleasure. This is due to his high dedication and hard work in establishing the

Microgravity Fluid Mechanics within the community of mechanical sciences, and due to

the particular evolution which this young but very promising discipline has had.

In the first phase the evolution was strongly related to the activities in other microgravity

sciences. For a wide spectrum of experiments under compensated gravity fluid mechanics

plays a very important role as at least one fluid phase is present in each experiment. This is

the case for example in the material sciences, where molten materials must be treated

adequately, in biology and biotechnology, in combustion sciences, in chemical engineering

and even in some medical experiments.

Through the emphasis of the past activities another microgravity discipline especially on

material science research, the microgravity fluid mechanics focuses on capillary mechanics

and on interface transport phenomena. But at the present Fluid Mechanics has recognized

that there is a wide spectrum of unsolved problems, which can be studied advantageously

in a microgravity environment. This is especially true for the investigation of many basic

fluid phenomena, which have been so far otherwise intractable because of gravity effects in

earth-bound research.

The evolution of Microgravity Fluid Mechanics cannot be better emphasized than by the

scientific programme of this Symposium. Fluid mechanical problems in the broadest sense

are treated: statics and dynamics of fluids with large free boundaries, Marangoni

phenomena, bubbles and drops, multiphase flows, mass and heat transfer in flow fields,

combustion, solidification and even non-newtonian flows.

In spite of this wide range of problems I feel that the topics discussed represent the bases

for the forthcoming of Fluid Mechanics in general. In this sense I would like to thank all

participants for the hard work in ensuring the success of this Symposium.
