The present numerical study is concerned with two-dimensional unsteady natural convective flow in a rectangular enclosure with a partially heated vertical wall. It has been assumed that the fluid is initially at a uniform temperature and motionless. Then, at time zero, the heated element is heated to a higher uniform temperature, while the opposite wall is held at the initial fluid temperature with the remaining wall surfaces being assumed adiabatic. The development of the flow following this temperature change has been studied numerically. Results have been obtained for a number of heat surface element sizes and locations, cavity aspect ratios, and Rayleigh numbers.
