Hydrodynamics and Heat Transfer Characteristics of Bio-Synthesized SiC-alka- Line Water and ZnO-alkaline Water Nanofluids in an Aluminum Plate Pin-Fin Heat Sink

The hydrodynamic and thermal performance of a heat sink constructed of an aluminum plate with pin-finned fins is investigated in this study utilizing two nanofluids, SiC-alkaline water and ZnOalkaline water. The heat sink core plate, which is used to cool electronic equipment, must have the following dimensions: 12 mm (length) x 40 mm (width) x 40 mm (length) (H). It is shielded from the weather by being contained in an aluminum plexiglass container that is insulated from the outside world with insulator foam. As a result, the heat sink's bottom surface gets a continuous heat flow of 118.9 kW/m2, while the nanofluid is pumped through it at the same constant input temperature. Following that, the thermal performance of the heat sink is evaluated. The nanofluids are generated at volume concentrations of 0.25%, 0.5%, 1.25%, and 2% with water serving as the foundation fluid, and their performance is evaluated. The heat sink's hydrodynamic performance was evaluated by comparing the pressure differential between the entry and exit sites to a reference pressure. According to the study, when SiC-alkaline water nanofluids were added to water at a rate of 2%, pumping power increased by 17% and 33%, respectively. Following the testing, the average heat transfer coefficients of the nanofluids under consideration increased by 18% and 16%, respectively, and decreased by 14% and 12%.
