Abstract

In this work we study the heat transfer and fluid flow process in a vertical cavity of large aspect ratio, \(AR=12\), with walls of finite thickness, heated from two portions localized in the side walls of the cavity near the bottom. The equations of motion are written in non-dimensional form, depending of four non dimensional parameters (the Rayleigh number, the Prandtl number, the ratio of thermal diffusivities of the fluid and the material of the cavity and the non-dimensional width of the walls) and are solved numerically by the use of the SIMPLE algorithm. Calculations are performed for three different values of the Rayleigh number.
