Abstract
Enclosure with an inlet at the base and an opposite outlet at the top was investigated numerically using finite element method. The heat was applied to the sidewall of the enclosure away from the inlet opening. The Richardson number was changed a number by the values (0, 1, 2.5, 5, and 10). For each Richardson number, Reynold number was changed into (25, 50, 100, 200, 300, 400, and 500) respectively. Average and local Nusselt number was determined during the investigation as well as the streamlines and the isothermal patterns. The results revealed that as value increases of Reynolds number in the enclosure the Nusselt number was also increased, the same way as Richardson number increased the Nusselt number in the enclosure increased.
