The interaction phenomenon between shock waves and discharge fields has a unique vortex generation effect in the supersonic flow fields. Understanding this phenomenon is crucial for engineering applications related to the supersonic flow field control. Previous studies have suggested a correlation between shock wave shape modulation phenomena and vorticity generation. Therefore, it is expected to measure vorticity based on shock wave configurations. For this purpose, simultaneously, temperature distribution measurement in the discharge fields is inevident. Our research group is exploring methods to measure temperature based on time-series visualization data using high-speed cameras. This paper introduces the results of improved measurement accuracy in velocity measurement techniques by using time sequential visualization data.
