Boundary condition at inlet

Hello everyone, I want to simulate turbulent flow in a horizontal channel. As per requirement I want to give fully developed mean velocity profile at the inlet. I am using OPENFOAM V6 in Ubuntu 18.04. Can you kindly tell me what should I do?

HI,

My inlet velocity profile is U=2.44ln(y)+5.5 for half channel width. Over the mean profile I will give the perturbation to obtain the instantaneous quantity. Can you give me any suggection?
