Sorry to say that you have no knowledge of what you are doing... If you prescribe at inlet a uniform velocity profile that is not a fully developed turbulent profile but is the inviscid (external)...

Yes, URANS is the formulation with the time derivatives in the equations. That assumes a different meaning of the averaging and must be described by a 3D formulation, not in 2D. However, try the 2D...

There are many contractidion in the approach you are using for this flow problem. You are assuming that the inlet averaged profile is a function of time, that is Uinf=U(0,y,t). That means you need to...

Still not clear what you are doing... 1) The velocity in time means you want to prescribe a uniform velocity in inlet of intensity that changes in time? 2) What means that your Re number varies...

The first help I can do is to ask you what you want simulate. Are you simulating a spatial evolving BL from laminar to transitional conditions or is the flat plate periodic? For a fully turbulent...
