Improvement of Accuracy of Temperature Measurement Method around Discharge Field Based on Shock Wave Velocity

Abstract

The shock wave mitigation technique by using the electromagnetic energy is one of the promising methods. The baroclinic effect has the important role in this method. This effect has the possibility to apply to the generation the vortex phenomena in the compressible flow field. Therefore, the comprehension of the effect is inevitable for exploring the further vortex control- ing application in the supersonic flow field. Until now, the temperature distribution measurement has been conducted in order to the comprehension of the baroclinic effect by the interaction between the shock wave and the temperature modulated field due to the electric discharge energy, based on the shock wave velocity. However, the conventional method depends on the Mach number at the down stream region of the discharged field. This Mach number has a large impact on the temperature determination.Based on this background, in this study, we tried to improve the temperature determination method. As a result, the determination accuracy improved.
