Abstract
Experimental and numerical studies of the effects of side-wall temperature on the flow pattern of Rayleigh Benard cells in a rectangular enclosure with an aspect ratio of 6 : 2 : 1 (length : width : height) are presented. Experiments were carried out using air at Rayleigh number≤16000. We have demonstrated that the flow pattern always consists of a steady even or odd number of roll-cells with axes almost parallel to the short or long side of the enclosure for all side-wall temperatures. The results of numerical calculations based on the steady three dimensional Boussinesq equations are in quantitative agreement with the observed flow patterns.
