Abstract
In this numerical study, the effects of inserting conductive arc-shaped baffles in a differentially heated, square cavity on natural convection heat transfer are investigated. The baffles are made from different materials such as aluminum, steel and wood. Rayleigh number is varied from 7x10 4 to 4x10 6 . The nondimensional radius of the baffle is also varied from R=0 (without partition) to R=1.12. The Fluent commercial code with Finite volume method is used to solve the governing equations of flow and heat transfer. It is observed that heat transfer, temperature distribution and fluid flow are affected by changing the radius of the partition with the maximum heat transfer obtained at R=1.
