Smart Control of Turbulent Combustion

The International Workshop on Turbulent Combustion was held September 14-15, 2000, at the Nagoya Institute of Technology, to review the present status of turbu lent combustion studies. Reviews were presented by Prof. F. A. Williams of the Uni versity of California, San Diego; Prof. Ken Bray of the University of Cambridge; and Prof. Jay Gore of Purdue University. Dr. Howard Baum of the National Institute of Standards and Technology and Dr. Jim McDonough of the University of Ken tucky participated in the discussion. Some ten papers, describing the latest findings of Japanese studies in this field, were given at the meeting. About half of these studies are supported by a national project, the Open and Integrated Research Pro gram, Creation of New Functionalized Thermo-Fluid Systems by Turbulence Con trol, that started only recently under the sponsorship of the Science and Technology Agency of Japan. The meeting was a great success and gave impetus and a sense of perspective to young Japanese researchers through the excellent reviews and valu able comments their work received. I believe that this kind of open discussion is indispensable for any project to produce a good outcome, and I would like to extend my sincere thanks to all who participated in the meeting. Finally, I would like to express my special thanks to Prof. Tatsuya Hasegawa of the Nagoya Institute of Technology, Prof. Akira Yoshida of Tokyo Denki University, Prof.

Topics cover the theory of turbulent combustion and active control of combustion by turbulence Emphasis on the fundamental understanding of the turbulent combustion and the design of an active controller to reduce the combustion oscillation

Klappentext

Turbulent flow occurs both in the environment and in many engineering problems. Understanding turbulent combustion and designing an active controller to reduce combustion oscillation is urgently required to save energy and to improve the environment. The work collected here gives valuable insight into how these challenges are being met by engineers who deal with gas turbines and industrial furnaces. Each paper, by an expert in the field, contributes to a better understanding of the chemical and physical processes involved in turbulent combustion. The chapters of the book present the fundamentals of turbulent combustion, the mechanisms involved, and control devices, all of which will assist in the design and development of turbulence control systems in the future. This book will be an especially valuable resource for those working in the fields of fluid dynamics, heat transfer, and combustion.
