Abstract

The steady flow of an ideal gas with finite conductivity past a thin wedge section in an aligned magnetic field is considered within the linearized theory. The wedge is assumed to be an insulator or a perfect conductor. The flow field around the obstacle is found by numerical integration of the Fourier transform for various values of the Mach number, the Alfven Mach number and the magnetic Reynolds number in the main stream. The outer flow is estimated by the method of asymptotic expansions. These results disclose how the inner flow including gas-dynamic features changes to the magnetohydrodynamic outer flow.
