dc.description.abstractThe increasing demands for higher performance and at the same time miniaturizing the high-power density electronic components have led to innumerable studies on hybrid nanofluid. This rising class of nanofluids demonstrated significant improvement when compared to individual nanofluids due to synergistic effect. Combination of hybrid nanofluid used in jet impingement which is known for removing high localized heat would further enhance the heat transfer abilities. Forced convection heat transfer of gold-base hybrid nanofluid with three most commonly used metal-oxide nanoparticles (TiO2, Al2O3 and ZnO) is investigated numerically for the jet impingement. This research focused on numerical investigation of optimum ratio for the hybrid nanoparticles for optimal ratio and the concentration of the mixture in order to obtain the highest heat transfer rate for impinging jet. Five different hybrid nanoparticles with ratio 10:0, 9:1, 5:5, 1:9 and 0:10 and concentration ranging from 0.005-0.02 vol% is implemented in this study. Each of the condition are tested under four different Reynolds numbers which are 4000, 8000, 12000, and 16000. It is worth mentioning that, the validation process of the results under similar condition demonstrated strong agreement with previously reported studies. The results also showed that all hybrid nanofluid performed better than utilizing base fluid. From the results, it is observed that the ZnO-Au/Water hybrid nanofluid with concentration of 0.02 vol% at Reynolds number 16000 is the best as it tremendously enhances the heat transfer rate by 24.05% compared to the base fluid, followed by Al2O3 with 19.43% and TiO2 with 15.39%. � 2023 American Institute of Physics Inc..
