wall function for twoPhaseEulerFoam
Hello Foamers,
as the title says I look for some good wall function using the twoPhaseEulerFoam solver. Right now I deal with y+ values around 0.001 to 10. I tried zeroGradient for k and epsilon, but I was not sure about the results. I tried to get higher values of y+ (above 30) for some walls and use the kqrWallFunction, but when I try to run the solver it says this wall function does not exist. Anyone knows how to add the function to the solver? Also, since I have a small slit with very low y+ values I thought of using a laminar case there. Is there a option in OpenFOAM to use two different solvers (1 laminar 1 turbulent) for the areas or do I have to run the case turbulent first then export the values at the slit inlet and outlet and rerun the slit in another case? Thanks for your time & help, |

Thanks Alberto,
I did look up the bubbleFOAM files now. For it seems that the solver always takes a wall function "if (isA<wallFvPatch>(currPatch))" (from the wallFunctions.H) I translated this line with "if a boundary is defined as a wall in the file constant/polyMesh/boundary What is the difference if I change the wall function in the /0 folder? |
