Organizers: Hiroshi Higuchi (Syracuse University, U.S.A.)

and Toshiyuki Hayase (Tohoku University, Japan)

Scope: Flow control is one of the research fields in which the rapid acquisition, computation, processing and application of fluid information form a critical role for further advancement of research. In this mini-symposium, the state of the art in flow control problems is discussed from the viewpoint of both experimental and computational approaches.
