Abstract :
We discuss gas heating effects in an anodic-pulse 4-kV 10-ns discharge interacting with a Mach 3 supersonic premixed O2-H2 boundary layer flow. Rapid gas heating occurs in the electrode near-field region with gas temperature increase on the order of 100 K-200 K. The rapid heating of the gas mixture results in micro blast waves which propagate into the free stream and eventually decay.
