How to find HTC in Flotran
 

I have two queries:
1.) Is it possible in Flotran to find the Heat transfer coefficient (HTC), if so, then how?
2.) In Flotarn one can give the wall roughness. But if I hve a square channel, is it possible to give wall roughness (say 0.25 mm) on only one side surface and remaining three side/surfaces are smooth.

Any help would be highly appreciated!

Regards.
