dc.description.abstractMostflows encountered in day to day life, in engineering practice and in nature are turbulent. One of the major modes of fluid flow in an enclosure is natural convection which is also the main mode of heat transfer. This research work will mainly use a rectangular enclosure which is bounded by walls to study turbulent natural convection. The research is going to help us get velocity and temperature distribution of the fluid flow in the enclosure. The energy equations and mass momentum with boussinesq approximations will be solved using k-w-sst model. Aspect ratio of 1.5, 1.0 and 0.75 and prandtl numbers and a constant Rayleigh number (RA) were used and the governing equations were solved. The results of streamlines, magnitude, vectors colored by temperature has been represented. As aspect ratio decreases the vortices and the fluid becomes more turbulent.en_US
