Mechanisms of Flow Control and Examples of Application Professor Xiao Ming Nanjing University of Aeronautics and Astronautics Nanjing 210016, China The idea of flow control is to effect large changes of flow condition via the use of small inputs of mechanical forces, mass, heat, or electro-magnetic forces. Flow instability and vortex dynamics play important roles in such processes. In this talk, I will review basic flow mechanisms that one can take advantage for the purpose of flow control. Several successful examples of flow control by my research group will be then presented. These include: 1) control of the wake behind a circular cylinder; 2) control of the transition of a boundary layer; 3) drag reduction by a wing-tip device; 4) synthetic jet and its application in flow control; 5) control of vortex symmetry over slender bodies at high angles of attack. About The Speaker Professor Xiao Ming received his BS degree in aeronautics in 1967 from the Northwestern Polytechnical University in China. The Chinese higher education system was practically brought to a halt during the Cultural Revolution that swept over the country between 1966 and 1976. Professor Ming, however, was one of the first few recipients of Ph.D. degree granted by the Chinese Department of Education after the government restored its higher education system in 1977. Professor Ming received his MS. and Ph.D. degrees in aerodynamics in 1981 and 1988, respectively, both from Nanjing University of Aeronautics and Astronautics, where he is currently a professor in the Department of Aerodynamics in the School of Aircraft Design. Professor Ming is a fellow of the Chinese Society of Mechanics. He has three patents and received a number of awards from the Chinese government for his research and inventions in the field of fluid flow research and applications. |
