摘要：In the present paper mixed convection fluid flow and isothermal lines of Al2O3-water nanofluid inside a square cavity with various inclination angles and lid's velocity ratio has been investigated numerically. The left and right side walls of the cavity were kept at Th and Tc, respectively, with Th>Tc. The top walls of the cavity moved from left to right in its own plane with a constant velocity Ut, while the bottom wall moved in its own plane from right to left with a constant velocity Ub. The velocity ratio was defined as Ub/Ut. The governing equations were discretized using finite volume method and the coupling between the velocity and pressure fields was done by SIMPLER algorithm
