In this study, the baroclinic effect due to the interaction between the shock wave and discharged plasma was investigated, from the view point of the vortex generation. For this study, the experimental apparatuses such as the power supply system for the discharged plasma generation, the measurement system for the interaction phenomena were developed. From the visualization results, the curved shock wave was observed due to the interaction with the discharged plasma. Also, the pressure signals suggested that the shock wave was deformed. This pressure signals consistent to the visualization result. From the numerical simulation, it was suggested that the curved shock wave due to the interaction with the discharged plasma was related to the vortex generation. This study suggests that the present results have a possibility to control the vortex generation by novel approach in the supersonic flow.
