The shock is generated by a sharp 15° wedge. Gas compressed by the incident and reflected shocks is sucked out at the rear wall and then injected in front of the interaction region through flat or axisymmetric nozzles. The following measurements are taken: pressure distribution over the test plate; stagnation pressure profiles at the end of the channel formed between the shock generator and the test plate; and pressure fluctuations in front of the interaction region, inside this region, and behind it. Although the separation is not eliminated, the passive control has a great influence on the flow in the interaction region. This results in an increase in the stagnation pressure in the near-wall flow zone, a more uniform pressure distribution over the plate surface, and a decrease in the maximum pressure and pressure fluctuation levels at the end of the interaction region. %8 2017-06-21
