Announcement of 2nd Symposium on Smart Control of Turbulence
DATE
March 4-6, 2001
1. Background of the Symposium
At present, three national research institutes carry out a study on Smart Control of Turbulence ("Smart Control of Turbulence: A Millennium Challenge for Innovative Thermal and Fluids Systems", Project for Organized Research Combination System by Ministry of Education, Culture, Sports, Science and Technology, Executive Manager: Hideo Ohashi, President, Kogakuin University, Steering Committee Chair: Nobuhide Kasagi, Professor, The University of Tokyo).
The purpose of this study is to realize the smart turbulence control, which should lead to tremendous technological impacts such as drag reduction and enhancement in combustion and heat transfer, by developing highly intelligent fluid-dynamic devices with new functions. This interdisciplinary research target can be fulfilled by the unique collaboration between three national laboratories, namely, NAL (National Aerospace Laboratory, Ministry of Education, Culture, Sports, Science and Technology), MEL (Mechanical Engineering Laboratory, National Institute of Advanced Industrial Science and Technology, Ministry of Economy,Trade and Industry), and SRI (Ship Research Institute, Ministry of Land,Infrastructure and Transport), each of which over the years has been playing a primary role in the R&D studies on numerical simulation of turbulence, MEMS technology, and functionalization of fluids, respectively. Leading scientists at several top universities will also join and help with this project.
2. About the Symposium
In this Symposium, invited speakers will give overviews on the recent study of smart control of turbulence and the speakers of the each research institutes will present following research targets: (1) conceptual design of micro devices for active feedback control of turbulence, (2) study on control of turbulent combustion, (3) turbulence control with mechano-chemical functionalization of fluids (surfactants, micro bubbles, ... etc.), and (4) large-scale numerical simulation of shear flow turbulence, turbulence combustion, and turbulence control mechanisms.
