Ionized gas flow for different forms of the law of its electroconductivity variation is studied in this paper. At first, it was considered that the gas electroconductivity was determined by the law $\sigma=\sigma(x)$. Then, under the influence of MHD, it is accepted that the electroconductivity variation law is determined by the expression $\sigma-\sigma_0(1-u/u_e)$. At the end, ionized gas flow is studied in the case when the electroconductivity of the gas is a function of the longitudinal velocity gradient. For all these cases boundary layer equations are, by means of suitable transformations, brought to a generalized form. The obtained universal equations are numerically solved in the so-called three parametric approximation. Based on the obtained solutions, behaviour of physical values and boundary layer characteristics are graphically presented. Conclusions are drawn about the influence of certain parameters on distribution of physical values in the boundary layer.
