矩形喷嘴产生的菱形激波

Application ID: 128791


In this example, the High Mach Number Flow, Low Reynolds Number k-e interface is used to compute the compressible turbulent flow from a rectangular nozzle. Mesh refinement based on the estimation of the shock strength and the shear-layer strength is employed to achieve appropriate resolution. The emerging turbulent supersonic jet has a shock diamond structure which attenuates along its axis due to growing turbulence viscosity. The asymmetry of the jet pattern between the minor and the major planes, and the entrainment of the surrounding low-speed flow are visualized.
