摘      要：The objective of this numerical work is to evaluate the first law and second law performances of a hybrid nanofluid flowing through a liquidcooled microchannel *** waterbased hybrid nanofluid includes the Fe_(3)O_(4)and carbon nanotubes(CNTs)*** heatsink includes a microchannel configuration for the flow field to gain heat from a processor placed on the bottom of the *** effects of Fe_(3)O_(4)concentration(φFe_(3)O_(4))CNT concentration(φCNT)and Reynolds number(Re)on the convective heat transfer coefficient,CPU surface temperature,thermal resistance,pumping power,as well as the rate of entropy generation due to the heat transfer and fluid friction is *** results indicated higher values of convective heat transfer coefficient,pumping power,and frictional entropy generation rate for higher values of Re,Fe_(3)O_(4)andφ*** increasing Re,Fe_(3)O_(4)and uCNT,the CPU surface temperature and the thermal resistance decrease,and the temperature distribution at the CPU surface became more *** achieve the maximum performance of the studied heatsink,applying the hybrid nanofluid with low Fe_(3)O_(4)andφCNT was suggested,while the minimum entropy generation was achieved with the application of nanofluid with highφFe_(3)O_(4)andφCNT.
