Modeling and Simulation of Coupled Plasma-Flow Interactions for Aerodynamic Actuation and Sensing

This talk presents an overview of modeling and simulation of plasma actuation and sensing of aerodynamic flow.  The physical attributes, e.g. momentum transfer requirements, of plasma actuators for different flow regimes ranging from low speed flows to hypersonic flow will be discussed and appropriate modeling approaches for flow, air plasma chemistry, and plasma dynamics will be presented.  The talk will then discuss computational challenges associated with the temporal/spatial stiffness of plasma-aerodynamic flow interactions and approaches to overcome these numerical issues.  Finally, the complementary problem of aerodynamic flow sensing will be introduced and a novel microwave plasma flow sensor concept will be developed using high-fidelity modeling.
