ABSTRACT = {A two-dimensional numerical study of laminar natural convection in a square enclosure filled with air with a wall partially heated on the bottom is presented. The heat source is located on the lower wall with different heated widths varied from 20 to 80%(ε = 0.2–0.8) of the total width of the lower wall and different heights h = H/4 and H/2 of the partition. The effect of the partition height on the main system dynamics is investigated through solution of the two-dimensional Navier–Stokes equations and the energy equation by means of a finite volume method based on the SIMPLE algorithm. The influence of the Rayleigh number (Ra = 10<sup>3</sup> to 10<sup>6</sup>) and the hot wall length is also examined. It is shown that the average Nusselt number grows when ε increases and when h decreases. For a given value of ε and h, the average Nusselt number increases as Ra increases. It is concluded that the partition height causes a decrease in the average Nusselt number.},
