A numerical approach called “SIMPLER” is used to investigate the flow and heat transfer characteristics in a square driven cavity. The two-dimensional incompressible Navier-Stokes equations were solved and the results are depicted as contour plots of stream function, vorticity, and total pressure for Reynolds numbers from 1 to 10000. At the higher values of Reynolds number, an inviscid core region develops, but secondary eddies are present in the bottom corners of the square at all Reynolds numbers. In addition, the energy equation was solved and isotherms and wall heat-flux distributions are graphically presented. The finding of the present numerical solutions with those given in the literature are in good agreement.
