Pin Fin Appatatus

The apparatus consists of a channel in which the pin fin is tested in both natural as well as forced convection. The channel is connected to the suction of blower. The blower is operated to touch the pin fin in forced convection only. In natural convection, the window above the pin fin is kept open to the atmosphere. Five thermocouple tapings are given along the length of the fin. Thus the temperature distribution along the length can be distinguished. Also natural and forced heat transfer co-efficient, effectiveness, etc. can be found out.
