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.
