“…The boundary layer area is replaced by a planar integration grid, so the values of the functions j, F, and h are calculated at discrete points of each calculating layer of this grid. A concrete numerical solution is performed using a programme written in FORTRAN, based on the one used in the paper [2]. Since the equation system is non-linear, it is solved by an iterative procedure.…”

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

“…Since, Prandtl number slightly depends on the temperature [5], the equations of the system (19) are solved for the constant value Pr = 0.712. For constants a and b, the usual values are adopted [4]: a = 0.4408 and b = 5.7140.…”

The ionized gas flow in the boundary layer on bodies of revolution with porous contour is studied in this paper. The gas electroconductivity is assumed to be a function of the longitudinal coordinate , x. The problem is solved using Saljnikov's version of the general similarity method. This paper is an extension of Saljnikov's generalized solutions and their application to a particular case of magnetohydrodynamic flow. Generalized boundary layer equations have been numerically solved in a four-parametric localized approximation and characteristics of some physical quantities in the boundary layer has been studied.

“…In its original version, it was successfully used for problems of planar flow in the dissociated gas boundary layer [3,4]. The method was then modified by Saljnikov [5]. Saljnikov's version of this method was applied in the MHD boundary layer theory for solution of different problems of bodies within electroconductive incompressible fluids.…”

This paper studies the influence of the magnetic field on the planar laminar steady flow of the ionized gas in the boundary layer. The present outer magnetic field is homogeneous and perpendicular to the body within the fluid. The gas of the same physical characteristics as the gas in the main flow is injected (ejected) through the contour of the body. The governing boundary layer equations for different forms of the electroconductivity variation law are transformed, brought to a generalized form and solved numerically in a four-parametric approximation. It has been determined that the magnetic field, through the magnetic parameter, has a great influence on certain quantities and characteristics of the boundary layer. It has also been shown that this parameter has an especially significant influence on the non-dimensional friction function, and hence the boundary layer separation point.
