The numerical investigation is based on two-dimensional (2D) compressible Euler simulation, which is initiated by a shock wave hitting a gas layer (curtain). We observe excellent agreements with the previous decay analysis on 2D viscous isotropic homogeneous turbulence at inertial range[2]. The baroclinic circulation in this environment plays a major role on the mass transport and mixing. The mass transport induced density gradient intensification, in turn, enhances the circulation baroclinically and
