Abstract
Two-dimensional steady-state buoyancy driven flows of thermo-dependent shear-thinning power-law fluid confined in a square cavity, submitted to cross uniform heat fluxes, has been conducted numerically using a finite difference technique. The parameters governing the problem are the thermo-dependence number m (0≤m≤10) and the ratio between the heat flux imposed on the vertical walls and that imposed on the horizontal ones represented by a (0≤a≤1), while the flow behavior index n is fixed at (n=1.4) and the Rayleigh number at (R_a=5000). The effects of these parameters on the flow structure and heat transfer characteristics have been analyzed.
