abstract ={In order to evaluate the ability of to simulate , mixed convective heat transfer of a in a square lid-driven cavity has been numerically studied. The governing equations were solved by , using . In this paper, the effect of parameters like the Grashof number, the volume fraction of , and ratio on the heat transfer of Al2O3-Water have been investigated. Also, to calculate fluid viscosity and thermal conductivity coefficient of the , the temperature-depended variable model was used, considering the Brownian motion of the particle. The results showed that the increase in amplifies the buoyancy force and enhances the Nusselt number as well as heat transfer rate. Also, the increase in viscosity at low Grashof numbers intensifies the forced convection and increases the Nusselt number over the hot wall. However, at Gr=105, the increase in viscosity up to K=1 leads to the decrease in the amount of heat transfer, but its further increase entails the increase in heat transfer. Although the addition of to the fluid improves heat transfer rate, the extent of improvement at is lower than that in the Newtonian . },
