Abstract: We have experimentally studied and numerically simulated the shock-wave flow that arises as a result of the development of a system of microchannels of pulsed sliding surface discharge in helium at low pressure. Using numerical simulations based on a solution of the system of regularized Grad equations (R13) and Navier–Stokes equations, results obtained for various Knudsen numbers are compared and it is shown that the influence of rarefaction on the discharge-plasma-induced shock-wave flow is manifested in a transient regime at Kn = 10$^{-1}$.
