Abstract:Natural convection heat transfer in inclined square cavity filled with thermo-dependent power-law fluids has been investigated numerically. The enclosure considered here is heated and cooled with uniform fluxes from the horizontal walls, while the verticals ones are adiabatic. The effects of the governing parameters, which are the thermo-dependence number (0 £ m£10) , the flow behavior index (n = 0.6) , the Rayleigh number (Ra =104 ) and the angle of inclination (0° £f £ 120°) , on flow structure and heat transfer characteristics have been examined. Results are presented in the form of treamline and isotherm plots as well as the variation of the Nusselt number under different conditions.
