2-D Laminar Natural Convection Heat Transfer in Different Tilt Angles and Aspect Ratios Using Staggered and Collocated Approaches

2-D laminar flow with natural Convection with different checker board removing approaches (staggered and collocated grid systems) is solved to provide comparison between staggered and collocated arrangements. SIMPLEC algorithm is employed for pressure velocity coupling. The results are first presented for a benchmark problem and then the effect of the inclination angle and aspect ratio are investigated. Mean Nusselt number, flow pattern and convergence characteristics are used for comparison. The convergence behaviour of two approaches is also tested for different Rayleigh numbers. Staggered arrangement generally had a better performance in that regard.
