Laminar free convection inside an inclined L-shaped enclosure

We have numerically reported the buoyancy induced flow and heat transfer characteristics inside an inclined L-shaped enclosure. A control volume based Finite-Volume method is applied to discretize the governing equations with collocated variable arrangement. SIMPLE algorithm is used and the system of equations is solved by Stone's SIP solver with full multigrid acceleration. Results are presented in the form of the average Nusselt number for a range of inclination angle, θ = 0°-360°; Rayleigh number, Ra = 1-105; and aspect ratio, A = 0.1-0.5.
