SWBLI at Near-Surface Stratified Plasma: Comparison of Test Results to CFD Modelling Data

This work is focused on shock wave - boundary layer interaction (SWBLI), pressure redistribution along a rectangular duct, and dynamics of a supersonic, M = 2, airflow structure under the impact of near-surface transient energy deposition (stratified plasma zone) in a shock-dominated airflow. The power deposition is provided by means of a Quasi-DC electrical discharge, which generates a filamentary plasma between flush mounted surface electrodes arranged in a spanwise array. The effect of reflected SW mitigation is demonstrated due to the interaction with the plasma-modified BL. The test data are compared to detailed flowfields simulated numerically.
