EN

The phenomena of combined convection within a lid-driven square cavity subjected to variable properties of nanofluid having a hot obstacle have been analyzed numerically. Finite volume method with SIMPLER algorithm is employed for solving the Navier-Stokes and energy balance equations. In this paper diameter of nanoparticles are uniform, constant and equal to 47 nm. Wide range of parameters such as Richardson number (0.01
