Abstract

Joint experimental and numerical investigation is performed to analyze effect of a localized DC-arc discharge upstream of blunt and sharp axisymmetric bodies on the flowfield structure and aerodynamic drag at Mach 5. DC arc power of W = 1.5 kW was realized for the flow control using thin tungsten-electrodes. Experimental investigations are conducted in the Ludwieg Tube Facility at DLR Göttingen. The numerical calculations are performed in the framework of the unsteady Euler equations.
