wind tunnel and simulation results different
 
Dear all

I simulated the flow over some buildings using an unsteady k epsilon realizable model. I also compare with a wind tunnel results. I find that the velocity values close to the building match well, but in the far stream values the velocity decreases but then slowly rise and then stay constant. But in the wind tunnel they slowly decay to a much lower value

I set a pressure outlet assuming fully developed flow . Any suggestions ?
