MAGNETOGASDYNAMIC SHOCK WAVES IN A NONIDEAL GAS WITH HEAT CONDUCTION AND RADIATION HEAT FLUX


The purpose of this study is to obtain a self-similar solution of the problem of the propagation of a magnetogasdynamic shock wave in a nonideal gas with heat conduction and radiation heat flux in the presence of a spatially decreasing azimuthal magnetic field strength. The initial density of the medium is assumed to be constant. The heat conduction is expressed in terms of the Fourier’s law, and the radiation is considered to be of diffusion type for the optically thick grey gas model. The thermal conductivity and absorption coefficients are assumed to vary with temperature and density. The shock is assumed to be driven by a piston moving with a variable velocity. Similarity solutions are obtained, and the effects of variation of the gas nonidealness parameter and Alfven–Mach number on the flow field behind the shock are investigated.
