摘要：The present study numerically simulates the mixed convection of the hybrid nanofluid (HNFs) of Al 2 O 3 /CuO–H 2 O on a simple heat sink (HS). The (HNFs) flow passes on an isothermal HS. The NF flow was treated as a slip flow on the upper wall. A uniform magnetic field influences the NF flow. The control volume method was employed with SIMPLE algorithm to solve the algebraic equations. For this purpose, the thickness of fins was changed between 0.1 and 0.3, studying four layouts for fins with different thicknesses. The results indicated that dispersing 3% volume fraction of hybrid nanoparticles (NPs) at a 1:1 ratio to the water enhanced heat transfer and entropy generation ( S g e n ) by 2.78% and 6.59%, respectively. Compared to Al 2 O 3 NPs, dispersing CuO NPs was approved that has a larger effect on heat transfer improvement. A change in the fin thickness or layout at different Richardson numbers (Ri) triggered different behavior in isotherms and S g e n .
