3D Supersonic Flow in a Channel With a Bump
Application ID: 43741
This example models 3D supersonic flow, including the effect of a shock, in a straight channel with a small obstacle on one of the walls.
As the flow hits the obstacle, shock waves are diffracted from the obstacle and walls of the channel. The propagating shock waves form a pattern in the velocity profile and density distribution.
The model makes use of the adaptive mesh refinement feature in COMSOL Multiphysics. This feature is important as the shock waves should be well resolved by the mesh, but predetermination of their position is difficult to determine.
Results are in good agreement with those published in literature.
This model example illustrates applications of this type that would nominally be built using the following products:CFD Module
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 Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
