xiaojun218 New Member zhuxiaojun Join Date: Oct 2009 Posts: 1 Rep Power: 0	I want to simulate a rectangular tunnel flow which has inlet and outlet velocities with k-omega model. The tunnel is long enough so the flow can be considered as full-developed.My question is how to set the inlet and outlet boundary condition to get good simulation. Actually I know how to set k and omega of the inlet through the empirical equation. But I am not very sure of the outlet boundary condition setting in some books. So can anybody give me a more accurate description of the outlet setting? Any reply will be appreciated. Regards xiaojun Last edited by xiaojun218; November 29, 2009 at 02:44.
