How to find the Nusselt number along a wall?

Sedullo · July 15, 2020, 07:42

I am running a case of Natural convection heat transfer between a hot vertical plate and the atmosphere.

I am using buoyantBoussinesqPimpleFoam, it is a laminar case, so the Grashof number is laminar and the turbulenceProperties are set to "laminar", so there is no RAS turbulence model.

I would like to find the value of the Nusselt Number along the wall, but in the previous discussion I did not find anything that could fit for my case.

My programming skills are quite limited so I kindly ask you to give me a sort of step by step explanation if you have some ideas.

Thanks for the help

you can calculate your nusselt number with paraview,
you need to choose the calculator and then type in
the equation.

Thanks for the reply, could you tell me please what should I write in the calculator?
