It is known that the baroclinic effect is caused by the interaction between a shock wave and a modulated density field due to the energy input to the flow field, and this phenomenon is expected to be applied to the shock wave-induced vortex generation technology for the supersonic flow control. Understanding the phenomenon of the interaction effect from the view point of the vorticity is important for the practical application of this technology. In this study, a method for quantitatively estimating the vorticity generated behind a shock wave based on the shock wave configuration was investigated by using CFD analysis. The vorticity field generated behind the shock wave in a uniform field agreed between the CFD results and the theoretically derived values based on the shock wave configuration. However, for non-uniform fields, some kind of discrepancy was observed between the conventional theory and CFD results. In the future, we will modify a theoretical method to estimate the vorticity under a non-uniform field.
