Multiple contraction of gas-discharge plasma in crevice channels

Shock wave interaction with pulsed glow discharge and afterglow plasmas

“…jump connected with the shock wave can result in local neutral gas heating causing the shock dispersion and the shock-speed increase [14][15][16]. Others argued that the thermal non-uniformities and temperature effects are the dominant mechanisms for the observed shock wave broadening and velocity changes in plasmas [17][18][19][20][21][22][23][24]. In a glow discharge plasma column, the temperature gradients (longitudinal and radial) and thermal non-uniformities are always present.…”
