Laminar natural convection in shallow open cavities
Experimental investigation on natural convection in a two-dimensional open cavity was performed using Laser Doppler Velocimetry. The cavity is rectangular with one vertical heated wall facing a vertical opening; the two horizontal walls are insulated. Studies for an open shallow cavity with an aspect ratio of 0.143 and Rayleigh numbers ranging from 10/sup 6/ to 10/sup 7/ under the laminar steady flow conditions were carried out using water as working fluid. Velocity profiles and heat transfer results obtained illustrate the effect of the open boundary which can be viewed as consisting of two parts, the outgoing hot fluid flow exhibiting strong characteristics of the cavity condition, and the incoming flow influenced by outside conditions. These findings compare favorably with numerical results.
