Abstract
A numerical study is presented for natural convection flow and heat transfer in a rectangular enclosure cooled from above with five discrete protruding heaters mounted on one vertical wall. The governing equations for natural convection and conjugate conduction within protruding heaters were solved using a finite volume method over a range of Rayleigh numbers from 5.0 × 105 to 1.0 × 107. Results showed the flow pattern and temperature profile within the entire enclosure for various power inputs, the correction of local Nusselt number versus modified Rayleigh number was presented. Comparison of the numerical results with experimental data showed good agreement.
