| description | Heat transfer enhancement has been a major concern in modern days in designing heat
generating equipment. In the present study an experimental study has been investigated
to analyze the thermal performance of plate fin arrays and pin fin arrays for solid,
circular and hexagonal perforations along the length of the fin in the turbulent flow
regime under steady state forced convection. The air velocity was varied ranging from
4ms-1 to 12ms-1 and data are recorded after a certain period of time at a constant heat
flux. The performance of plate fin and pin fin as heat sink was tested and best result was
found in case of pin fin with hexagonal perforation heat sink.Convective heat transfer coefficient, fin effectiveness, fin efficiency seem to increase in hexagonal perforation both
for plate fin and pin fin arrays. Thermal resistance seems to decrease in hexagonal
perforation than circular perforation and solid fins. This study suggests that most
important parameter that governs the performance of fin is the fin geometry and varied
cross section i.e. perforations. |
