Abstract: The present work is devoted to the study of the influence of an electrical DC discharge applied over a flat plate subjected to a supersonic and rarefied air flow. The main topic of this paper concerns the 2D Navier-Stokes numerical simulation of the flow developed around the model and submitted to the effects induced by the presence of glow plasma created above the flat plate. Different effects like, surface plate temperature, gas volume temperature and plate geometry, were considered in the numerical simulation and compared with the experimental results obtained in a wind tunnel producing a laminar Mach 2 air flow at ambient pressure equivalent to the 80 km altitude atmospheric pressure.

Keywords: supersonic flow; plasma flow control; experimental study; rarefied regime; Navier-Stokes numerical simulation; shock modification; DC discharge; electrical discharge; modelling; surface plate temperature; gas volume temperature; plate geometry; aerodynamics.
