On the ionized gas boundary layer adjacent to the bodies of revolution in the case of variable electroconductivity

Abstract

This paper studies the ionized gas i.e. air flow in an axisymmetrical boundary layer adjacent to the bodies of revolution. The contour of the body within the fluid is nonporous. The ionized gas flows under the conditions of equilibrium ionization. A concrete form of the electroconductivity variation law has been assumed and studied here. Through transformation of variables and introduction of sets of parameters, V. N. Saljnikov's version of the general similarity method has been successfully applied. Generalized equations of axisymmetrical ionized gas boundary layer have been obtained and then numerically solved in a three-parametric localized approximation

Analysis of the axisymmetrical ionized gas boundary layer adjacent to porous contour of the body of revolution

“…• Behavior of the characteristic boundary layer function F mp ( fig. 7) is as expected and as usual [28]. In order to obtain more accurate results, the system (18) should be solved in a fourparametric approximation but without localization per the compressibility parameter, but this is fraught with difficulties, mainly of numerical nature.…”

“…6). By variation of the input parameters, assuming that the electroconductivity is the function of the longitudinal co-ordinate x, it has been concluded that the magnetic field will not postpone the separation of the boundary layer, as in [26][27][28][29]. • Behavior of the characteristic boundary layer function F mp ( fig.…”
