A self-similar solution of dissipative MHD for a jet in the boundary-layer approximation

A solution of dissipative nonlinear MHD taking account of the balance between viscous drag, the Lorentz force, resistive diffusion and inertia in a boundary-layer approximation is presented. It is a steady solution corresponding to a jet in a conducting fluid with viscosity. The problem is solved us...
