This study conducts a detailed CFD analysis of the thermo-hydraulic performance of a Mini Channel Heat Sink (MCHS) cooled using a ternary hybrid nanofluid comprising Fe3O4, Al2O3, and ZnO nanoparticles dispersed in water. The thermophysical properties of the nanofluid are derived from experimentally developed correlations. The effects of volume fraction and Reynolds number on heat transfer and pressure drop were investigated. Furthermore magnetic field effect on the Ternary nanofluid is also discussed. Results indicate that the ternary nanofluid significantly enhances heat dissipation but increases viscosity and pressure drop due to nanoparticle dispersion, particularly at higher Reynolds numbers. The application of a magnetic field further improves heat transfer with minimal additional pressure drop. The study found that at a Reynolds number of 1900, the Nusselt number increased by 15 %, 25 %, 36 %, and 46 % for volume fractions of 0.5 %, 0.75 %, 1 %, and 1.25 %, respectively, compared to water. Similarly, the pressure drop was higher by 22 %, 44 %, 112 %, and 218 % for the same volume fractions. These findings highlight the potential of ternary hybrid nanofluids in optimizing thermal performance in MCHSs. |
