turbulent channel flow
I am trying to modeling the turbulent channel flow. I set the size af channel by 10*1. The Reynolds number is 13750.My boundary conditions are inlet, two walls, and outlet. I supposed that the inlet velocity is 1 m/s (Uniform velocity). It results in that nu is 2.27*10^-5 (u*D/Re).
I used the k-epsilon model for this approach.
but my results are similar to laminar....,
please help me.
please, plot your velocity profile at outlet in wall-unit, that is U+(Y+). Use a semi-log scale. Your inlet is an inviscid plug-flow therefore you have a double spatially developing boundary layer over flat plate, not a real turbulent channel flow...
