We will simulate the generation if a normal shock wave in a de Laval nozzle. A shock wave occurs when supersonic flow can not maintain the regime anymore when the pressure downstrem is too high. To match the outside pressure, an non isentropic process happens in which the fluid properties change suddenly. In the case we will be studying, a nozzle expands air below 0,1 bar when the outside pressure is 1 bar, so a normal shock wave occurs.

The lid-driven cavity problem has long been used a test or validation case for new codes or new solution methods. The problem geometry is simple and two-dimensional, and the boundary conditions are also simple. The standard case is fluid contained in a square domain with Dirichlet boundary conditions on all sides, with three stationary sides and one moving side (with velocity tangent to the side).

Tutorial project for a flow analysis of a pipe junction. The project only provides the geometry to start with. See our tutorials section to have a look at the step-by-step instructions to set up the simulation.
