Calculation of heat transfer coefficient of natural convection in 2D vertical plate
 
Hi,

I am wondering if there is tutorial or example case of openFOAM to calculate heat transfer coefficient of laminar natural convection in 2D vertical plate, whose approximate analytical solution is often introduced in textbooks of heat transfer.
(such as Nu = A(Pr)*Ra^(1/4))

Of course, I understand that such a solution is derived based on assumptions that CFD perfectly does not emulate (infinite length, open boundary conditions etc).
Even approximately, I need similar example case.
(buoyantSimpleFoam or buoyantBoussinesqSimpleFoam's one)

If you know, I would appreciate it if you could tell me the case.

Thank you in advance,
Sincerely.

Here's a 3D tutorial for a confined natural convection case. It should be pretty straight forward to make it 2D. https://github.com/OpenFOAM/OpenFOAM.../buoyantCavity

I appreciate your kind reply, and it is very helpful because there is a reference.

Thank you so much.

Sincerely.
