They dont give the same result if the wall temperature or heat flux is not constant. I just tried that in CFX. My alternative expression recovers the area average of the heat transfer coefficient in...

So you were already aware of this and used the expert parameter? Then I have some doubt about the expression you use for calculating the average heat transfer coefficient manually. Instead of:...

Sorry for being a little unclear. I just thought that when comparing heat transfer coefficients manually calculated from wall temperatures and heat fluxes to the...

Not sure if this is related to your problem, but the last time I used CFX for heat transfer simulations I had to activate the expert parameter "Tbulk for HTC". Otherwise, CFX takes a temperature...
