摘要
In this paper, numerical simulation of conjugate heat transfer of water-copper nanofluid is performed in a microchannel using two-phase lattice Boltzmann method (LBM), in which viscous dissipation is considered. In this study, the intermolecular forces such as drag, Brownian force, buoyancy, Van der Waals and Born forces are studied and analyzed. The magnitude of these forces is estimated and their degree of importance in the simulation is determined. Further, the effect of increasing the volume fraction and nanoparticles diameter on heat transfer and fluid flow is investigated. Finally, the effect of thermal conductivity of the microchannel’s wall on Nusselt numbers is investigated.
