Abstract
Numerical studies of glow discharges were carried out to evaluate their utility for flow control applications. As part of this project, a three-dimensional computer code has been written to solve the fluid conservation laws, the charged particle continuity equations under the drift-diffusion model, and the Poisson equation for the electric potential. Glow discharge calculations have been carried out in the absence of flow, exploring the effects of background pressure, applied magnetic fields, and finite electrodes. With the presence of a Mach 5 crossflow, three-dimensional computations have identified the origin of the downward force in a plasma flap concept as dissipative heating in the vicinity of the cathode, and rough agreement has been obtained between numerical predictions and experimental measurements of the total temperature rise in that region. A simplified actuator model has been applied in the numerical exploration of the control of a Mach 14 compression ramp flow, and suitable actuator locations and power levels have been identified.
