rdbhaxor is on a distinguished road
I am trying to create model of Numerical Simulations of Flow and Heat Transfer Over Rib-Roughened Surfaces. Here is the model



The problem i am facing with calculating average nusselt no . I have the relation but it gives same value for all Reynolds no. If any one can give some insight into this .

If any one need i can provide the comsol file.

Thanks in advance.
