Hello,

I’m reading the pag. 34 of this PhD Tesis*

And it says that “a constant heat transfer coefficient is used for the thermal boundary condition. The value of the coefficient was chosen so that simulated replications matched the experimental values using reverse engineering.”

As far as I know, when simulating a flow using a multiphase model, it is NOT possible to set the heat transfer coefficient constant between the wall and the fluid, because it is calculated at each time step.

I have contacted the author and he said me that he set the h value constant.

I use ANSYS Fluent and I really think that this is not possible, is it possible in CFX? As far as I know, it is not!

I will appreciate your help!
