My model is a cooling channel heated by copper from the top and bottom. The heat flux was used at the endwall surface of the top and bottom. The flow is turbulent.
The local Nu can be plotted by Nu = hD/k
Where D is hydraulic diameter and k is thermal conductivity of fluid
h is heat transfer coefficient calculated by q/(Tw-Tb)
q is heat flux (W/m^2) (What is the name of this parameter in COMSOL? i.e. ht.cflux...)
Tw is local wall temperature (K)
Tb is bulk temperature (K) (how to calculate?)
