MAGNETOGASDYNAMIC CYLINDRICAL SHOCK WAVES IN A ROTATING NONIDEAL GAS WITH RADIATION HEAT FLUX

A similarity solution is presented for a cylindrical magnetogasdynamic shock wave in a rotating nonideal gas in the presence of a variable axial magnetic field in the case where the radiation heat flux is of importance. The initial angular velocity of the medium is supposed to vary as some power of the distance from the symmetry axis. The radiation heat flux is evaluated from the equation of motion without an explicit use of the radiation transfer equations. It is shown that the gas nonidealness increases the shock strength, but decreases the shock velocity. On the other hand, the presence of a magnetic field decreases the shock strength, but increases the shock velocity. Moreover, the shock velocity increases with the ratio of specific heats. The total energy of the shock wave increases with time.
