摘要

Natural convection heat transfer and fluid flow in a two-dimensional enclosure filled with Cu-water nanofluid has been analyzed numerically. An incompressible generalized lattice Boltzmann method was utilized to solve the velocity field, while heat transfer was simulated using the single-relaxation-time lattice Boltzmann method (SRT-LBM). Different models were used to describe the viscosity and thermal conductivity of nanofluid. The results were compared to show the effect of these two parameters in numerical simulations.
