Magnetohydrodynamic Cylindrical Shock In A Rotational Axisymmetric Non-Ideal Gas Under The Action Of Monochromatic Radiation

摘要

A self-similar MHD cylindrical shock wave is investigated in a non-uniform rotating non-ideal gas under the action of monochromatic radiation. The fluid velocities and the initial magnetic field of the ambient medium are assumed to be varying and obeying power laws. The gas is assumed to be non-ideal having infinite electrical conductivity and as the distance from the axis increases the angular velocity of the ambient medium decreases. Also, when the surrounding medium is of constant density then only similarity solutions exist. It is investigated that increase in the non-idealness of the gas, the adiabatic exponent of the gas and the strength of ambient magnetic field have decaying effect on the shock wave. Also, it is observed that an increase in the non-idealness of the gas and adiabatic exponent of the gas has same effect on the flow variables except the radial component of fluid velocity, the pressure and the magnetic field.
