Model-based feedback control of vortex shedding at low Reynolds numbers

By: Simon Illingworth (University of Melbourne)

Model-based feedback control of vortex shedding at low Reynolds numbers is considered. Using 2-D DNS and reduced-order modelling techniques, linear models of the wake are formed and then used to design feedback controllers. As well as demonstrating the efficacy of control, the talk will also show that it becomes increasingly difficult to achieve acceptable control performance—measured in a suitable way—as Reynolds number increases. Although the talk will focus on control of the cylinder wake, I will also look at how similar methods can be used in thermoacoustics.
