I’m working on a heat sink with applied heat source at the bottom, i’m facing a difficulty in getting the heat transfer coefficient using FLUENT?.
hello, in my opinion the heat transfer coefficinet as calculated by fluent is not usefull. really I always calculated the heat transfer coefficient using my own definition but using the basic parameters from fluent, for example the mass average temperature at inlet and outlet sections, LMTD, and so on.
Ruben Borrajo Volodymyr Brazhenko i’m Working in a natural convection over a cross fin heat sink there is a heat source applied at the bottom. For the heat transfer coefficient do I write an expression of the heat flux (get it from fluent directly) over the difference in temperature. I didn’t get actually how the heat transfer coefficient and the heat flux is calculated in ANSYS. Thank you.

Volodymyr Brazhenko thank you, but if I have a heat source applied at the bottom of the heat sink should I consider the bottom when getting the heat transfer coefficient?.
