I have tried to reproduce the plane Poiseuille configuration (100*2) m in Fluent, I have to compare laminar and turbulent test case with DNS data.
I have begun with laminar 2D test case (Re_m= 5400), I specified the boundary condition as follows, at the inlet à velocity = velocity magnitude = 30 m/s (in x direction), at the outlet à zero pressure outlet, at the top and back wall à no-slip stationary.
After running, the profil is not parabolic!
Could anybody please explain what went wrong?
thanks a lot.
