As well known, heat transfer coefficient is q/A_s*(Twall-Tref). The problem is Tref. If we set up the reference in fluent as inlet condition, Tref is inlet temp. I think the reason why differently calculated when i calculate heat transfer coefficient. So now i want to get heat transfer coefficient using UDF, is it possible?? if is it possible would you help me how to express? Thanks and Regards
