Abstract

This paper considers the symmetrical heating of two vertical parallel surfaces for a Grashof number range of 10³ to 10⁵ with a Prandtl number of 0.7 and slot height-to-width ratios of 1.0 and 2.0. A non-orthogonal curvilinear coordinate system in conjunction with an adaptive grid method and second order accurate discretization schemes were employed in the numerical method. The entire flow field is modeled, including the region beneath the parallel surfaces, the region between the parallel surfaces, The outflow region above, and the eventual wake. The adaptive grid systems show clear evolution of the grid distribution pattern with respect to the change of Grashof number. A converging/diverging pattern can be identified within the slot. The effect of aspect ratio on the flow characteristics is also observed.
