Abstract
Free convection heat transfer from circular solid and hollow/perforated pin fin heat sinks with different geometry and heat flux is numericallystudied using FLUENT ANSYS 16.0. The geometric dependence of heat transfers from heat sinks of solid and hollow/perforated fins with staggered pattern, attached on a fixed area heated base plate is discussed. A SIMPLE code is developed using control volume approach to solve governing equations (mass, momentum and energy), and the second order upwind technique is used. The results were carried out for a range of Rayleigh number, 9.3×106> Ra> 1.63×107. It showed that the performance of the hollow/perforated fin heat sink is higher than that for the solid fin heat sink. It is also investigated that hollow/perforated fin array with inner-to-outer diameter ratio (Di/Do=1/2) and perforation diameter (dp < /sub> < /sub>=6 mm) is the best sample giving the maximum performance and less amount of weight compared to the corresponding solid ones
