NUMERICAL STUDY OF THE EFFECT OF A NANOFLUID WITH NANOPARTICLES OF NONUNIFORM SIZE ON NATURAL CONVECTION IN AN INCLINED ENCLOSURE
RÉSUMÉ
Heat transfer and fluid flow with natural convection in an inclined cavity with variable size Al2O3 nanoparticles are studied. Moreover, the influence of the nonuniform size of nanoparticles, inclination angle, nanoparticle volume fraction, Prandtl number, and of Grashof number on heat transfer rates is examined. The angle of inclination of the cavity between 0° to 120° is considered. Computations show that the average Nusselt number increases with the Rayleigh number and that the average Nusselt number decreases as the nanoparticle mean diameter increases at all angles except 90°. The results show that the change in the nanoparticle size and angle of inclination affects the natural convection heat transfer in a rectangular cavity.
