Abstract
We have studied the formation of vortex structures and the development of turbulence behind the front of a shock wave with Mach number M = 1.5–3.0 moving along a near-wall gas layer excited by a nano-second pulsed transverse surface discharge within 40–500 μs after initiation. Schlieren images of the flow are compared to the results of two-dimensional numerical simulations based on the Navier-Stokes equations and a pulsed energy deposition model.
