A shock wave inaweakly ionized gas can be preceeded by acharge separation region if the Debye length is larger than the shock width.
It has been proposed that electrostatic contributions to pressure in the charge separation region can increase the sound speed ahead of the shock well above the sound speed in a neutral gas at the same temperature and therefore increase the shock.

NON-IDEAL GAS EFFECTS ON SHOCK WAVES IN WEAKLY IONIZED GASES ROBERT RUBINSTEIN* AND AARON H. AUSLENDERt Abstract. A shock wave in a weakly ionized gas can be preceeded by a charge separation region if the Debye length is larger than the shock width. It has been proposed that electrostatic contributions to pressure.

glow discharge plasma to weak (non-ionizing) shock waves of Mach number in the range - 3. Our results show that there is an increase in the velocity of a shock wave when it makes a transition from a neutral gas to a weakly ionized plasma.
The observations also indicate that the shock acceleration cannot be accounted for by thermal effects only. Similarity Solutions are obtained for one-dimensional adiabatic flow behind ionizing cylindrical shock wave propagating in a rotating non-ideal gas in presence of an azimuthal magnetic field.
The electrical conductivity in the medium ahead of the shock is assumed to be negligible, which becomes infinitely large after passage of the shock. In order to obtain the similarity solutions. On imploding cylindrical and spherical shock waves in a perfect gas By N.
