Pin-fins are effective strategies to enhance heat sink performance; moreover, bio-inspired designs present endless geometrical potential. In this work, a comparative investigation of two biomorphic pin-fin-based heat sinks was carried out via ANSYS CFD simulations. The results showed that the heat transfer performance of the pentagonal and sharp-edged design reported approximately 14% higher Nusselt number compared to a circular and smoother-edged design. Furthermore, the pressure drops or variations within both heat sinks were minimal. The findings from this research provide a baseline for future bio-inspired heat sink designs and heat transfer improvement strategies.
