Abstract
Natural convection fluid flow and heat transfer inside C-shaped enclosures filled with Cu–Water nanofluid has been investigated numerically using finite volume method and SIMPLER algorithm. A parametric study was conducted and effects of pertinent parameters such as Rayleigh number, the aspect ratio of the C-shaped enclosure, and the volume fraction of the Cu nanoparticles on the flow and temperature fields and the rate of heat transfer inside the enclosure were investigated. It was found from the obtained results that the mean Nusselt number increased with increase in Rayleigh number and volume fraction of Cu nanoparticles regardless aspect ratio of the enclosure. Moreover the obtained results showed that the rate of heat transfer increased with decreasing the aspect ratio of the cavity. Also it was found that the rate of heat transfer increased with increase in nanoparticles volume fraction. Also at low Rayleigh numbers, the effect of Cu nanoparticles on enhancement of heat transfer for narrow enclosures was more than that for wide enclosures.
