报告摘要:Steady state two-dimensional mixed convection in a lid-driven square cavity filled with Cu-water

          nanofluid is investigated numerically in the presence of internal heat generation. In the present

          investigation, bottom wall is uniformly and non-uniformly heated while two vertical walls are fixed

          and they are thermally insulated. The top wall is moving from left to right at a constant speed. The

          governing equations are normalized and solved numerically with boundary conditions by finite volume

          approach using third order accurate upwinding scheme (deferred QUICK). Effects of the pertinent

          physical parometers are investigated in terms of  the flow and temperature fields, as well as Nusselt

          number distributions. The presented results show that the solid volume fraction plays a significant

          role on the flow and thermal fields and the Nusselt number distributions for different flow

          configuratiions. It is found that Richardson number strongly affect the fluid flow and heat transfer

          in the cavity. For Ri<1, the forced convection becomes dominant in the entire cavity, the natural

          convection relatively weak.
