Control of Fluid Flows

Organiser: Miroslav Krstic (University of California - San Diego)

The advances in micro-electro-mechanical systems (MEMS) now make it possible to control turbulent fluid flows. Mathematical tools for designing intelligent control strategies are unfortunately lagging behind technological development. The reason for this is the notorious complexity of Navier-Stokes partial differential equations modeling fluid flows. This session gathers leaders in this field that pursue distinctly different leaders in this field that pursue distinctly different paths towards designing controllers. Topics such as stabilizing turbulence by control and sensing from the fluid boundary, control of mixing of different fluids, and open loop transfer of a fluid from one (steady) state to another will be covered.
