Hi every Foamers,
I would like to run a steady-state external aerodynamics in Atmospheric Boundary Layer, using the Prandtl's one-equation model with L the mixing length being proportional to the wall distance (something similar to wallDist(mesh_) from LES PrandtlDelta ). But I can't find any RAS turbulence models (incompressibleRASModels, Foam user guide p.U-100) corresponding! The unique 1 equation model is Spalart-Allmaras but seems very complicated for me. Does anybody has already implemented the Prandtl's one-equation model for RAS incompressible model ? It seems quite simple to do so. Do you know why it has not been done within OpenFOAM ? |
