Hey everyone I am simulating flow and heat transfer in a Square. I need to calculate Nusselt number at the heating surface.The heat transfer is naturel convection. I tried to calculate Nusselt number using Report>Surface integrals>Surface nusselt number But the Nusselt number I am getting is absurd.Is there any way to calculate Nusselt number?
and How i get average Nusselt and local Nusselt?
thanks
Djilali

Can you do an area-averaged surface integral for the Nusselt number? I bet it's integrating a bunch of dA's and not normalizing the sum w.r.t. surface area.
