Numerical Investigation Of transient Natural Convection In partitioned cavity filled with water

Transient natural convection in partitioned cavity filled with water is investigated numerically in this paper. The fluid flow and the heat transfer expressed in terms of continuity, linear momentum and energy equations were calculated by using the finite volume method. Prandtl number and Rayleigh number are fixed at 6.64 and 3,77x10(9), respectively, and the partition length of L/4. To approach the physical reality experience, calculations were performed in a cavity with the same size and same priority of the fluid with the temperature imposed on the cooled wall is equal to the average temperature T-m, also another calculations with the temperature imposed on the horizontal walls is equal to the average temperature T-m. The achieved results demonstrating the effects of the partition for the heat transfer and the thermal boundary layer are shown and discussed, it illustrate that the existence of the partition on the hot wall influences both heat transfer and fluid flow.
