Abstract
In present paper, certain aspect of shock wave in non-ideal gas, when magnetic field is orthogonal to the trajectories of the gas particles and electrical conductivity is taken to be infinite, is investigated. Considering one-dimensional unsteady non-planer motion, basic equations, its general solution and formation of shock-wave, conservation laws and jumps conditions, variation of area of non-uniform cross section and analytical solution of strong non planer shock is obtained.
Highlights
The assumption that the medium is an ideal gas is no more valid when the flow takes place in extreme conditions

Anisinov and Spiner [1] have studied a problem of point explosion in low density non ideal gas by taking the equation of state in a simplified form which describes the behaviour of medium satisfactorily
Summary
The assumption that the medium is an ideal gas is no more valid when the flow takes place in extreme conditions. Assuming that the piston is moving with time according to law given by Steiner and Hirschler [3], Vishwakarma et al [4] have investigated the one dimensional unsteady self-similar flow behind a strong shock, driven out by a cylindrical or spherical piston in a medium which is assumed to be non-ideal and which obey the simplified Vander-Waal’s equation of state as considered by Robert and Wu [5]. Re-entry problem of intercontinental ballistic missiles and supersonic projectiles are two engineering applications of such flows Because of such engineering applications many engineers and aerodynamicists joining the astrophysicists and geophysicists have extensively studied the dynamics of electrically conducting gases moving in a magnetic field. Since ae is larger than a speed of sound for ideal gas case, the shock wave formation will be faster in magneto-gas-dynamics for non-ideal gas
