    To analyze two dimensional incompressible laminar natural convection in a rectangular enclosure heated from below and cooled by a horizontal ceiling and two vertical walls, the primitive Navier-Stokes equations and the energy equation were solved numerically in time dependent form by a marker and cell method. A successive over-relaxation method for the elliptic portion of the problem and an explicit method for the parabolic portion were applied for the range of Grashoff number of 5×10³ to 5×10⁴ to get the transient and steady state dimensionless temperature and velocity profiles.
    For the range of aspect ratio L/H≦2.4 in which only a pair of convection rolls exists mean Nusselt number calculated are as follows :
    N_(NU)=0.89 N^(0.2)_(Gr) (H/L)^(0.45)
    By path lines drawn by marker particle trajectories roll number of cellular motion were observed for various aspect ratio of the enclosure.
