Non-ideal Gas Effects on Shock Waves in Weakly Ionized Gases Robert Rubinstein ICASE, Hampton, Virginia Aaron H. Auslender NASA Langley Research Center, Hampton, Virginia Institute for Computer Applications in Science and Engineering NASA Langley Research Center Hampton, VA Operated by Universities Space Research Association January Abstract.

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.

Besides shock waves in gases, the distinctive features of shock propagation through a weakly ionized plasma are considered.

A gas-ionizing cylindrical shock wave, generated by line ex-plosion, is propagated in the nonideal gas. The counter. Although most applications involve molecular gases, the dispersion effects with a comparable intensity are observed in noble gases. Interaction of shock wave with ionized gas generates rapidly moving multiple electric layers, which form regions of increased electron : L.

Vušković, S. Popovićs. Experimental studies of shock waves in weakly ionized plasmas were performed in longitudinal continuos or pulsed glow discharges.

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.
