Canonical Flows 2 | Turbulent Mixing Layer, AMR (OpenFOAM)
Canonical Flows...

"A mixing layer develops between tw OpenFOAM case parameters mesh: blockMesh solver: pimpleFoam turbulence model: LES (WALE) Adaptive Mesh Refinement (AMR) is the process of dynamically adapting the accuracy of a solution in certain areas of interest specified via some criteria. The idea of AMR is to get the simulation accuracy of a fine mesh while keeping the computational costs as low as possible. For this simulation I injected dye (or a passive scalar) through one of the inlets, this way I use the interface of the two streams as my refinement criteria. This method work particularly well for this simulation, but it may be necessary to use another criteria, like turbulent viscosity, in other cases. The cases and video presented are for educational purposes and should serve as a launching point in conducting and setting up your investigation.

In this video I go over some bounda I show you how to compute inflation layer parameters (number of cells, growth ratio, first cell height) from initial conditions (velocity, kinematic viscosity, skin friction coefficient, etc..) and desired y+ (yplus) and provide a python code for this.
