Sure you will get a reasonable answer from CFX for this kind of simulation.
When specifying a convective boundary condition, the FEA software will require Tbulk and the heat transfer coefficient....

I will try to make it more clear.

Lets forget about Tbulk and heat transfer coefficients for now.
What CFX and any other CFD software does is to calculate the heat flux at a surface. This is the...

The value for Tbulk is not all that important.
You only have to know which value for Tbulk you used if you want to compare values of the heat transfer coefficients to similar simulations or...
