I am using realizable k-e model with enhanced wall treatment now. I know k-e model not good for boundary simulation, but how about the realizable k-e model with enhanced wall treatment. Does realizable k-e model with enhanced wall treatment work well with surface roughness simulation? Is this correct model. If not, which turbulence model I should use? I have try SST K-W model but the result seems not good. Thanks.
