Assessment of temperature measurement method by applying one-dimensional Riemann problem

Abstract

In this study, the feasibility study for the temperature measurement method of the discharged field was conducted by using the CFD analysis. As a result, the estimated temperature by applying the Riemann problem can reproduce the temperature given as a initial condition for the CFD within at most 10% error. From this investigation, it is expected to apply this method to the experimental measurement. Especially, by combing with the high-speed camera visualization, it is expected to improve the experiment efficiency by conducting the two-dimensional measurement. Also, it is necessary to investigate the experimental accuracy of this technique by comparing the other measurement method such as the spectroscopic technique for the representative region.
