Abstract

An electric discharge is applied to generate a plasma spike in front of a wedge. Use of this plasma spike to modify the shock wave structure in a supersonic flow over the wedge is then studied. It is shown that the plasma spike can effectively deflect the incoming flow before the flow reaches the wedge; consequently, the shock structure in the interaction region is modified from an oblique to a curved shape. Moreover, the shock becomes detached as the strength of the plasma spike exceeds a critical level.
