Heat transfer modeling with kOmegaSST at walls
Hello everyone,
I try to figure out, how the heat transfer through a wall is calculated in fluent when using the kOmegaSST model. Unfortunately, there is nothing given in the fluent manuel. Is the laminar flow equation used, because yPlus is around 1?

Yes, with Y+1 you are able to solve the laminar sublayer.

Thanks for your replys. However, now I have found another problem on this topic:
I want to calculate the heat transfer coefficient. fluent can derive it automatically, but again I am not able to find the formulation. It should be h=(T_wallT_inf)/q_dot, where q_dot=(T_wallT_p)/dn where T_p is the temperature derived in the first cell from the wall and dn is the distance normal from the wall. What value does T_inf have? Is it the same as T_p? Is there any reference to validate how it is calculated?

So I can define T_inf in fluent?

Quote:
The wall heat flux and surface temperature are determined from the solution. The heat transfer coefficient is then calculated by applying Newton's law of cooling and using Tref (the reference temperature specified in the reference values).
