Title: Flow Invariance Preserving Feedback Controllers for Sabra Shell Model of Turbulence
Speaker: Dharmatti Sheetal (IISER TVM)
Date: 17 February 2017
Time: 11 am
Venue: LH-1, Mathematics Department

In this talk, I would continue dealing with Sabra shell model of Turbulence and study one of the important questions for fluid flow problems namely, finding controls which are capable of preserving the invariant quantities of the flow. Controls are designed in the feedback form such that resultant controlled flow will preserve certain physical properties of the state such as enstrophy, helicity. We use the theory of nonlinear semigroups and represent the feedback control as a multi-valued feedback term which lies in the normal cone of the convex constraint space under consideration.
