Shock wave modulation due to discharged plasma using a shock tube

The interaction phenomenon between shock waves and the DC-discharged plasma was experimentally investigated to aid future supersonic aerodynamic performance improvements. A shock tube was used to generate the shock wave. For the discharged plasma generation, a wedge type test model with electrodes (...
