An electric field model developed for multi-physics plasma-fluid simulation for atmospheric dielectric barrier discharge actuators

Immersed bodies such as struts and vanes in gas turbine flow systems will, except at the lowest of flow velocities, shed separated wakes. One means to mitigate this is through active flow control by the use of pulsed DC plasma actuation. A two-dimensional, plasma-fluid model and code, multi-PHysics Analysis of Fluid-plasma Numerical Integration algoRithm (PHAFNIR), that couples electrodynamics, plasma reaction kinetics, and fluid mechanics has been developed and validated extensively to experiment. Further, numerical verification has also been performed on this code.
