    Self-similar cylindrical shock waves with radiation heat flux (1984)
    Springer
    Astrophysics and space science 102 (1984), S. 263-268

    Notes: Abstract Similarity solutions describing the flow of a perfect gas behind cylindrical shock waves with radiation heat flux are investigated. The total energy of the expanding wave has been supposed to remain constant. The solution, however, is only applicable to a gaseous medium where the undisturbed pressure falls as the inverse square of the distance from the line of explosion.

    Self-similar problem with increasing energy in radiative magneto-gas dynamics (1984)
    Springer
    Astrophysics and space science 105 (1984), S. 161-170 
    Details

    Topics: Physics
    Notes: Abstract In the present paper self-similar solutions have been investigated for the propagation of piston driven, radiative gas-dynamic shocks into an inhomogeneous ideal gas permeated by a current free azimuthal magnetic field for spherical symmetry. The effects of radiation flux and magnetic field together have been seen in the region of interest on the other flow variables. The total energy of the flow between the piston and the shock is taken to be dependent on the shock radius obeying a power law. The radiative pressure and energy have been neglected. This problem is more general than the others done so far. The word piston implies some means to drive plasma radially onwards.

    Propagation of magnetogasdynamic spherical shock waves in an exponential medium (1979)
    Springer
    Astrophysics and space science 63 (1979), S. 253-259 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract In this paper propagation of magnetogasdynamic spherical shock waves is considered in an exponentially increasing medium. The shock wave moves with variable velocity and the total energy of the wave is variable. It is shown that the magnetic field changes the flow velocity, density and pressure.

    An explosion model in magne to gasdynamics (1980)

    Topics: Physics
    Notes: Abstract By taking into account the interaction with magnetic field, in an axially symmetric inhomogeneous medium and assuming Gaussian density profile in radial direction instead of the cusped exponential law, a point explosion has been investigated by generalising the method suggested by Laumbach and Probstein (1969). The shock envelope becomes increasingly elongated along the axis of rotation, until it finally breaks through into the intergalactic space before it can spread considerably in equatorial directions as in ordinary gasdynamics. A comparison has been made between our results and those obtained in ordinary gasdynamics. Explosion models of double radio sources and related objects are suggested.

    Notes: Abstract In this paper propagation of spherical shock waves with radiation heat flux is considered in an exponentially increasing medium. The shock wave moves with variable velocity and the total energy of the wave is variable. For different values of radiation parameter, the numerical solution has been made and the nature of the field variables are illustrated by the tables.

    Notes: Abstract The problems of central stellar explosions under the assumption that the temperature gradient is zero in the rear flow field have been studied. Also, the similarity solutions of the field variables for the homothermal flows of a self-gravitating gas behind the spherical shock-wave propagating in a non-uniform atmosphere at rest are obtained. The total energy of the wave is taken to be time-dependent obeying a power-law.

    Notes: Abstract Similarity solutions, for one-dimensional unsteady of a perfect gas behind a spherical shock wave produced on account of a sudden explosion or driven out by an expanding piston including the effects of radiative cooling and an idealised azimuthal magnetic field, are studied. The shock is assumed to be strong and it is propagating into a transparent medium at rest with varying density. The magnetic field is proportional tor −1. The total energy of the wave is time dependent obeying a power law.

The model has been considered here in which the magnetic field is proportional tor −1, but the total energy of the wave is of the increasing order, not constant.
