Hi,

How to calculate heat transfer coefficient on adiabatic surface in fluent. For example; I send 50 santigrad and 10 m/s air on surface as a parallel flow. when I assigned 10 santigrad on surface, there exist heat flux on surface due to temperature difference and I calculate heat transfer coefficient easily. But there are not heat flux on adiabatic surface in fluent. Heat flux is zero. How to calculate HTC on adiabatic surface.

The term "adiabatic" means that there is no heat flux across the boundary. So why are you trying to compute the heat flux using an adiabatic assumption. If you choose adiabatic, then you have already determined that the heat flux is zero. If I am misunderstanding your post then forgive me, but it sounds like the solver is behaving like it should.

I am not sure about the sense of the question, the heat flux is zero because is zero the normal derivative while the heat coefficient is not vanishing?
