Effect of MHD System Arrangement on High Speed Plasma Flow Structure around Conical Body

摘要

Efficient and reliable control of aerodynamic characteristics of a body flying at super- or hypersonic speed is a challenging problem of perspective high speed vehicles development. One of feasible ways of such a control is MHD impact on plasma flow around the body. In the Ioffe Physical Technical Institute of Russian Academy of Sciences during last decade experimental and numerical investigations of supersonic plasma flow around "cone-cylinder" body have been carried out. Effect of external magnetic field induced by a coil installed inside the body and of electric discharge rotating in the magnetic field on cone surface between electrodes locating on the cone apex and cone-cylinder conjugation has been considered. This paper is devoted to numerical analysis of the influence of arrangement of the magnetic coil and the electrode system installed in the model body on the high speed plasma flow around the body.
