How to determine fin efficiency (any shape of fin) by Fluent?
Heat exchanger is with finned tubes. Cold air is streming around tubes and hot water in tubes.
Can you help with solving attached problem. C1 and C2 is two different materials. B1=1500 J/cm heat input B2=2000 J/cm heat input A1 is first case with three measurement of hardness of the...
