چکیده:

Two–dimensional steady-state simulations of laminar natural convection in a square enclosure with differentially heated side walls subjected to constant wall temperatures have been conducted. The enclosure is completely filled with non-Newtonian fluids obeying the power-law model. The effects of power-law index n in the range 0.6 < n < 1.8 on heat and momentum transport are investigated for different Rayleigh numberof 104 to 106 and a Prandtl number of 100. It is found that the obtained results are in a good agreement with those of in the literature
