inlet for turbulent boundary layer
hi, all,

I am using FLUENT to simulate turbulent boundary layer, the turbulent intensity is 0.5%. To set the velocity inlet, I use UDF to profile k and epsilon at inlet. K and epsilon are calculated by turbulent intensity and velocity magnitude which will increase according to y+. However, the result is not good, can anybody give some suggestions? Many thanks
