Abstract
In this paper, the thermal and hydrodynamic performances of an aqueous ammonia base-nanofluid (Al2O3-NH3(aqu)) cooled in a rectangular microchannel heat sink was numerically investigated. The range of Reynolds number used in the investigation were between 140-1400. In order to assess the performance of the system during the employment of the proposed nanofluid, H2O and Al2O3-H2O were also tested and their performances were compared to Al2O3-NH3(aqu) performance in terms of thermal resistance and pressure drop. Results from the simulation showed that the proposed nanofluid outperformed pure water and slightly higher than Al2O3-H2O in terms of thermal resistance (for Re = 1400, 0.0474, 0.0449 and 0.04647 oK/W for H2O, Al2O3-H2O and Al2O3-NH3(aqu), respectively). However, it exceeds the performance of both pure water and Al2O3-H2O in terms of pressure drop (for Re = 1400, 785288, 911217, 753591 Pa for H2O, Al2O3-H2O and Al2O3-NH3(aqu), respectively). The key findings from the current study may be used to attract more research about the proposed nanofluid to be used in the cooling process of microchannel heat sinks.
