PARTICLE EFFECTS ON CONVECTIVE HEAT TRANSFER OF NANOFLUIDS IN A MICROTUBE
RESUMO
Literature searches revealed no studies that systematically examine how particles affect microscale convective heat transfer of nanofluids. This paper presents a numerical study on the particle effects on forced convection of nanofluids through a microtube. A thermal-flow model is firstly built and solved by using the marching implicit (MI) procedure. The computational results reveal that the particle concentration and interaction effects are to increase the pressure drop (or reduce the volume flow rate); moreover, for a fixed volume flow rate, the effects are to enhance the heat transfer. The role of particle interaction becomes more significant when the particle concentration increases and could be found to result in an increase in convective heat transfer.
