THE EFFECTS OF NUSSELT, REYNOLDS NUMBER, AND PRESSURE DROP ON THE THERMAL PERFORMANCE OF PIERCED PIN FINS

Perforated fin forced convection heat transfer is the primary focus of this investigation. The purpose of this research is to see if perforated pin fins can help with heat transmission in the devices. Each pin's perforation diameter and number of holes are rigorously examined. The Nusselt numbers for perforated pins are 47 percent higher than those for solid pins, according to the study, and this number raises as the number of holes increases. The pressure drop is reduced by 19% when perforated pins are used instead of solid pins. Heat transmission in a round-holed pin fin was studied using forced convection in tests. Perforations in the shape of circles were among the options available. For the sake of this investigation, a number of perforations were made. For example, all of the fins and readings have one to four perforated holes. Perforated fins can promote heat transfer because of the improved Nusselt number, increased convective heat transfer coefficient, and decreased pressure gradient provided by this model is 40% smaller and up to 85% more effective at transferring heat. As a result, eddy currents are lessened.
