Abstract
In this numerical investigation, the impacts of complete and partial cylindrical fin configurations on the thermohydraulic performance of a minichannel heatsink are studied. ANSYS Fluent software is used to conduct numerical analyses for four distinct mass flow rates ranging from 0.00265 kg/s to 0.0045 kg/s and three distinct fin positions. The effects of various configurations on velocity and temperature fields, average Nusselt number, Nusselt number ratio, friction coefficient, and performance evaluation coefficient are analyzed. According to the study’s findings, using partial cylindrical fins has a substantial impact on both heat transfer and pressure drop. When evaluating heat transfer, MCHS-R2a produces the greatest results, but this configuration greatly raises flow resistance. MCHS-R2c was found to have substantial potential when evaluated in terms of thermohydraulic performance.
