Abstract:
The heat transfer and fluid flow of natural convection in an inclined cavity is carried out using variable size of Al2O3 nanoparticle. Moreover the influence of non -uniform nanoparticle size, effect ofinclination angle, nanoparticle volume fraction, Prandtl number, and Grashof number are examined forheat transfer rates. The angel of inclination consider between 0 to 120 and computations show that the average Nusselt number increases with growth of Rayleigh number and the average Nusselt numberdecrease as mean nanoparticle diameter increases at all angels except 90 degree. The results show that the change on nanoparticle size and angel of inclination affects on the natural convection heat transfer in rectangular cavity
