The mixed convection fluid flow and heat transfer in lid-driven rectangular  enclosures filled with the Al2O3-water nanofluid is investigated numerically.  The left and the right vertical walls as well as the top horizontal wall of  the enclosure are maintained at a constant cold temperature Tc. The bottom  horizontal wall of the enclosure, which moves from left to right, is kept at  a constant hot temperature Th, with Th>Tc. The governing equations written in  terms of the primitive variables are solved using the finite volume method  and the SIMPLER algorithm. Using the developed code, a parametric study is  performed and the effects of the Richardson number, the aspect ratio of the  enclosure and the volume fraction of the nanoparticles on the fluid flow and  heat transfer inside the enclosure are investigated. The results show that at  low Richardson numbers, a primary counterclockwise vortex is formed inside  the enclosure. More over it is found that for the range of the Richardson  number considered, 10-1-101, the average Nusselt number of the hot wall,  increases with increasing the volume fraction of the nanoparticles. Also it  is observed that the average Nusselt number of the hot wall of tall  enclosures is more that to that of the shallow enclosures
