| Abstract | ||||
| This paper examines the mixed convection in a square cavity filled with different nanofluids. The lower side is stationary and was equally divided into a pair of heat source–sink; the left and right vertical sides are be insulated and have opposed velocity whilst the upper side is stationary and insulated. Steady state laminar regime is considered, the transport equations for continuity, momentum, energy are solved. The numerical results are reported for the effect of Richardson number, and solid volume fraction on average Nusselt for various parametric conditions. This study was done for 0.01 ≤ Ri ≤ 100, and 0 ≤ λ ≤ 0.06 while the Prandtl number represent water is kept constant at 6.2 and Grashof number at 104. A comparison is made with the previous published results. The comparison shows good agreements with previous published results. | ||||
