Abstract
I n this study, a numerical analysis carried out to determine the effects of arc-shaped partitions in corners of a shallow cavity on heat transfer which is natural convection and fluid flow. Partitions are accepted as conductive and two different partitions materials are chosen as wood and aluminum. The finite volume approach is used to discretize the governing equations for Rayleigh numbers Ra and shape ratio of the arc-shaped partition. It is found that arc-shaped partitions have effect on characteristic parameters of fluid flow and heat transfer. Specially, aluminum arc-shaped partition affects the average heat transfer enhancement, because it has high heat transfer coefficient. Also, possibilities of occurring dead regions are examined and streamlines obtained for without partitions and high Rayleigh numbers which are Ra=105 and Ra=106 show that dead regions occur in corners of the shallow cavity. Results obtained from the analysis using partitions and considering different Rayleigh numbers and partition materials show that using partition which is arcshaped prevent occurring dead regions
