Similarity solutions are obtained for one-dimensional cylindrical shock wave in a self-gravitating, rotational axisymmetric non-ideal gas with azimuthal or axial magnetic field in the presence of conductive and radiative heat fluxes. The total energy of the wave is non-constant. It is obtained that the increase in the Cowling number, in the parameters of radiative as well as conductive heat transfer and the parameter of the non-idealness of the gas have a decaying effect on the shock wave however increase in the value of gravitational parameter has reverse effect on the shock strength. It is manifested that the presence of azimuthal magnetic field removes the singularities which arise in some cases of the presence of axial magnetic field. Also, it is observed that the effect of the parameter of non-idealness of the gas is diminished by increasing the value of the gravitational parameter.

导热和辐射热通量作用下自重旋转轴对称非理想气体中的磁动力指数冲击波

在存在导电和辐射热通量的情况下,在具有重力或轴向磁场的自重力旋转轴对称非理想气体中,针对一维圆柱体冲击波获得相似解。波的总能量是非恒定的。结果表明,在辐射以及传导热传递的参数和气体的非理想性参数中,整流罩数的增加对冲击波具有衰减作用,但是重力参数的值具有对冲击强度的反作用。可以看出,方位磁场的存在消除了在轴向磁场存在的某些情况下出现的奇异性。也,
