Abstract

The purpose of this study is to investigate the heat and flow profile of nanofluid flow inside multilayer microchannel heat sink. Two different cooling fluid; water and water-based Aluminum Oxide is compared. The heated surface of the heat sink is set as constant heat flux of 200W/cm² and mass flow rate is varied as 20, 40, 60 and 80kg/hr. From the results, it shows that the use of Al₂O₃ nanofluid is better in terms of heat transfer compared to water because the percentage of increment of Nusselt number is higher (83%) compared to the percentage of increment of friction factor (23.5%). Therefore, Al₂O₃ nanofluid is better in terms of heat transfer compared to water but the pressure drop is still a drawback as it is higher compared to water.
