Wall pressure distribution

Karthik

Hi friends,

I have a bluff structure kept over a wall. I use RNG k epsilon turbulence model with non equilibrium wall functions.

Actually the pressure distrubutions ahead of the body on the base walls seems more correct than at the back. Behind the body on the base wall there is enormous difference between actual and computed value.

Could you please suggest what would be the probable cause and some remedy.

Thanks Karthik
