STUDY OF TOW DIMENSIONAL LAMINAR NATURAL CONVECTION INSIDE CAVITY

Abstract

An incompressible fluid flow and heat transfer by natural convection inside a rectangular cavity had been studied numerically. The study focused on the variation of velocity vectors and temperature values due to the change of Grashof number and an enclosure aspect ratio. The Grashof numbers was ranging from 103 to 105. Nusselt number dependence on temperature field especially near hot and cold walls is verified. The continuity, momentum and energy equations have been solved using finite volume method (FVM). The results show that the central core region is distorted with increase of Grashof number. Also the results indicated that the rate of heat transfer is increased with the increase of Grashof number. The validation of the computed results is verified through the comparison with the published results.
