This study numerically explores the flow physics associated with nanosecond pulsed plasma actuators to control shock-wave induced boundary-layer separation. By using two actuators, parallel and canted with respect to the main flow direction, a previous experiment suggested the actuator worked in two ways: boundary layer heating and vorticity production. The heating effect was enhanced with the parallel electrode and made the separation stronger, while the canted electrode produced vorticity and…
