NATURAL CONVECTION HEAT TRANSFER IN A NANOFLUID FILLED INCLINED L-SHAPED ENCLOSURE

In this investigation, Control Volume based Finite Element Method is applied to simulate the effects of different governing parameters on natural convection heat transfer in an inclined L-shape enclosure filled with Cu-water nanofluid. The numerical investigation is performed at a fixed Prandtl number (Pr) equal to 6.2 and various values of non dimensional governing parameters namely, volume fraction of nanoparticles, Rayleigh number and different inclination angles. The results show that for Ra =104 the maximum and minimum average Nusselt number correspond to ζ = -45ͦ and 45ͦ, respectively, whereas an opposite trend is observed for Ra =105.
