非均一He-Ar混合気中における衝撃波の数値計算

抄録

In explosion accident accompanied by detonation, concentration distribution inevitably exists in the mixture. Although detonation in such non-uniform mixture has been studied in various researches, basic understanding on the shock wave flow of a non-uniform multicomponent system such as fuel and air is lacking. In this study, we investigated the structure and characteristics of the shock wave propagating in the mixture of helium and argon with a concentration gradient normal to the propagating direction.
