Forced convection heat transfer through a double-layered microchannel heat sink has been numerically simulated using computational fluid dynamic method by ANSYS-fluent 2021 R2 software. The three main aspects have been studied. Different channel geometries have been investigated under the same boundary conditions. The result demonstrated that the current proposed hybrid geometry channel shape with triangular lower channel and rectangular upper channel showed the lowest thermal resistance. In addition, the optimal coolant type was investigated by comparing water, (Al₂O₃/H₂O, SiO₂/H₂O, Cu/H₂O) nanofluids and (Al₂O₃-SiO₂/H₂O, Al₂O₃-Cu/H₂O) hybrid nanofluids at a fixed Reynolds number and different volume concentrations (1%, 2.5% and 4%). It was proved that hybrid nanofluid has the lowest thermal resistance, specifically (Al₂O₃-SiO₂/H₂O) attained the lowest base wall temperature of about (297.7K) at 4% volume concentration due to its low capacitive thermal resistance. Throughout this study, the two classes of hybrid nanofluid thermophysical properties correlation were examined, correlations that include particle size (d_p) in thermal conductivity and dynamic viscosity equations and others neglecting it. The  results indicated that involving metallic particle size enhances the thermophysical properties as higher thermal conductivity and dynamic viscosity values are obtained that directly influence the thermal resistance and pumping power.
