This study numerically investigated the thermal and hydraulic performances of the air-cooled heat sink with slotted solid/aluminum foam compound cylindrical (SS/AFCC) fins in the staggered arrangement for various slot heights, thicknesses, and pore densities of the aluminum foam insert in the range of 150≤Re≤600. A steady-state 3D simulation of the proposed heat sink was developed in the COMSOL Multiphysics to conduct the above parametric investigation. The obtained results indicated that the SS/AFCC finned heat sink achieves a significant enhancement in heat transfer with affordable pressure drop compared with the heat sink with slotted solid cylindrical (SSC) fins. While an increase in the slot height and thickness caused a positive impact on the Nusselt number and pressure drop, the same effect was not observed when the pore density of the aluminum foam insert was increased.
