Abstract
Proper dissipation of thermal energy has always been a requirement for better efficiency of a system. Fins provide additional surfaces to reject heat to the surrounding from the working faces. The current work considers the thermal analysis of pin fins of circular and drop-shaped cross section. Fins of uniform cross section are placed over a base plate arranged in a staggered manner. With an analysis of various thermal and flow parameters, the drop-shaped pin fin is found to yield a better thermal enhancement over cylindrical pin fins. Further, the drop-shaped fins are modified to make a split to enhance the interaction between the fluid and the fin surface. The modification shows slightly better result compared to existing drop-shaped fin. The modelling has been done using ANSYS FLUENT 17.1.
