iŽam simulating flow forces on a spool in hydraulic valve with cfdesign (blue ridge numerics)
so i have problems with the validation of my results! cfdesign is using in the k-eps-model wall functions to simulate the turbulent flow next to a wall can somebody explain to me how the Y+ Value works and why ? e.g. -> what happen if the values outside the range given by cfdesign (35 < y+ < 350) -> Y+ values to low: should i unrefine the mesh, which variables are under- or overpredicted -> Y+ values to high: refine the mesh? -> etc. mfg Matthias |
