Question

Does heat transfer coefficient increase with temperature?

Answer 1

Answer:

As the position x increases, the thickness of the thermal boundary layer increases, i.e. the temperature increases over a greater distance y. Thus, the temperature gradient decreases in the x-direction and so does the local heat transfer coefficient.
