Abstract


The problem of mixed convection heat transfer of nanofluid in a lid driven square cavity containing several heated triangular cylinders is studied numerically using the finite volume discretization method. The upper and bottom walls are thermally insulated while the left and right walls are cooled at constant temperature, T_c. The present investigation considered the effects of pertinent parameters such as; size and number of the heated triangular cylinders on the flow and Nusselt number. The other parameters governing the problem are the Richardson number (0.1? Ri ? 100), the Prandtl number of the pure water (Pr = 6.2) and the volume fraction of nanoparticles (0 ? ? ? 0.05). Results show that increasing size and number of the heated triangular cylinders leads to increase the heat transfer rate. It is also found that by reducing Richardson number and increasing the volume fraction of nanoparticles, the average Nusselt number increases.
