EXACT SOLUTION FOR A MAGNETOGASDYNAMICAL CYLINDRICAL SHOCK WAVE IN A SELF-GRAVITATING ROTATING PERFECT GAS WITH RADIATION HEAT FLUX AND VARIABLE DENSITY

An exact similarity solution for a magnetoradiative cylindrical shock wave in a self-gravitating rotating perfect gas is obtained. The density, azimuthal velocity, and magnetic field strength are assumed to vary in an undisturbed medium. It is shown that the flow variables, namely, the radial velocity, pressure, magnetic field strength, azimuthal velocity, mass, and the radiation flux, decrease from the highest values at the shock front to zero, however, the density tends to infinity, as the symmetry axis is approached. The effects of variation in the magnetic field strength, gravitational parameter, rotational parameter, and in the adiabatic exponent on the flow variables and shock strength are discussed. The solutions obtained for self-gravitating and nongravitating media are compared. The total energy of the shock wave is shown to be not constant.
