Abstract
We give buoyancy induced flow pattern and heat transfer characteristics inside an L-shaped enclosure with differentially heated isothermal walls. The integral form of the governing equations are solved by control volume based finite volume method using SIMPLE algorithm and Stone's SIP solver. Flow and thermal fields are presented in the form of streamlines and isothermal lines for Grashof number ranges 10 to 10 6 . Three different values of interwall spacing are selected. Prandtl number of fluid is kept constant (=0.7). Unicellular flow pattern is observed at very low Grashof number. Corners of the enclosed space divide the unicell into two distinct cells (one horizontal and one vertical) at moderate Grashof numbers. Multicellular flow is observed at high Grashof number. Interwall spacing greatly affects the growth of multicellular pattern at high Grashof number. Local and average Nusselt number distribution present the heat transfer rate
