Abstract

The character of flow over a body, structure of the perturbed zone, and flow resistance in a supersonic flow of rarefied partially ionized gas are determined by the intrinsic magnetic field and surface potential of the body. The effects of intrinsic magnetic field and surface potential were studied in [1–4]. There have been practically no experimental studies of the effect of intrinsic magnetic field on flow of a rarefied plasma. Studies of the effect of surface potential have been limited to the case R/λd<50 [1, 3]; this is due to the difficulty of realization of flowover regimes at R/λd>102 (where R is the characteristic dimension of the body and X is the Debye radius). At the same time R/λd>102, the regime of flow over a large body, is of the greatest practical interest. The present study will consider the effect of potential and intrinsic magnetic field on resistance of a large (R/λd>102) axisymmetric body (disk, sphere) in a supersonic flow of rarefied partially ionized gas.
