CFD analysis of pylon equipped by plasma module for combustion in supersonic airflow

Abstract

Abstract Two new geometrical configurations of pylon equipped by plasma module for combustion in supersonic airflow were developed and discussed. This paper presents the results of three-dimensional CFD simulation of the flow around the pylon. The simulation was performed for two modifications of pylon and two possible geometries of set of three pylons. No fundamental difference was found between the two pylon geometries. It was shown that in one case of the installation of three pylons it provides continuous flow around the pylons, which should ensure stable operation of the plasma generator. In the second case of the arrangement of the pylons, the obtained flow structure promotes faster mixing of fuel with air; however, a significant separation zone is formed behind the pylons, which may impede the stable operation of the discharge.
