Abstract
The temperature deduction method from the visualization data using the correlation between the shock wave velocity and the temperature was investigated and compared with the rotational temperature measured by the emission spectroscopy. The temperature deduced from the visualization data in the case with the discharge (31.9 [W]) was 800 [K] which was significantly higher than that (300 [K]) in the case without the discharge (0 [W]). However, there was discrepancy with the temperature obtained from the emission spectroscopy. In spite of this discrepancy, with some improvement, the temperature deduction method can be a promising method, since this method can deduce the temperature in the region where even the emission signal is weak and cannot determine the temperature from the emission spectroscopy.
