曲衝撃波背後流れ場と衝撃波形状の関係理解

The baroclinic effect is caused by the interaction between density gradients and pressure gradients, and it is expected that the effect has a lot of applications of shock-wave-induced vortex phenomena in supersonic flows. Therefore, phenomenological comprehension of the effect is crucial. Previous research has shown that the shock wave is curved due to the interference of a shock wave with a modulated density field, and a relationship between the shock wave curvature phenomenon and vortex generation has been suggested. In this study, we evaluated the curvature of the curved shock wave and the vorticity behind the shock wave, and investigated the relationship between the curvature and vorticity by numerical analysis.
