Description
Heat transfer plays an important role in industrial and engineering applications. In this research, the effect of aluminum oxide nanoparticles on the forced heat transfer rate in laminar flow in a square cross-section channel is investigated. The governing equations are discretized by the finite difference method on the shifted grid. Nanofluid flow is simulated using single-phase and mixed models. Simulation results show that the average Nusselt number increases with the increase in Reynolds number. In addition, the average Nusselt number and consequently the heat transfer rate increase with the increase in volume fraction. The results of the mixed model are closer to the laboratory results than the single-phase model.
