Shock Diamonds from a Rectangular Nozzle
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.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille des Spécifications and make use of a free evaluation license.
