Please, I need help. I want to apply LaunderSharmaKE to an external flow for a blade section of a marine propeller. I found the tutorial nacaAirfoil (tutorials/compressible/sonicFoam/ras) but I can't adapt it to my incompressible case. What's the problem? I'm afraid it's about T or \rho in fvSchemes and fvSolution files (I got these system files from a \kappa-\epsilon case).
I attach my case (I delete polyMesh folder otherwise the file is too big).

Hi,

I have found this in the tutorials folder of OpenFOAM version 1.7.x. Hope it can help you.

OpenFOAM/OpenFOAM-1.7.x/tutorials/incompressible/boundaryFoam/boundaryLaunderSharma

Do you know the validity range of y+ for LaunderSharma ?

Best regards,

Stephane.

Thanks for your report, I'll check it out.
LaunderSharmaKE is a lowRe turbulent model, so I think your average y+ has to be around 1.
