衝撃波伝播速度に基づく温度場計測手法の可能性検討

抄録

The assessment of the simple temperature estimation theory based on the shock wave propagation velocity was conducted based on the comparison with the CFD simulation of the shock wave propagation through the temperature modulated field at the region from y=0 m to y=0.018m. The temperature estimated by the theory using the shock wave propagation velocity calculated from the CFD was compared with the initial temperature distribution given in CFD. This temperature estimation theory can predict the temperature distribution within at most 30 % error, for the present temperature field. The assessment suggests that the estimation error due mainly to the two dimensional effect should be paid attention for applying the theory.
