Volume of fluid method open foam
finite volume method is a discretization scheme for a flow domain in which a set of equations apply. The equations are usually non-linear, and for fluid problems, they are the transport equations. The finite volume method subdivides the flow domain into a finite number of contiguous control volumes. The open-source CFD library OpenFoam® contains a method for solving free surface Newtonian flows using the Reynolds averaged Navier–Stokes equations coupled with a volume of fluid method. The water density will be set to kg/m3. Ideally, we would like to set the air density to zero for our stream function test case, but numerical stability issues limit how low we can set the air density. We choose an air density of 1 kg/m3, which is close to the real physical value.
