Summary

Natural convection of air in a tall vertical cavity was studied using a smoke pattern and interferometry. Experiments covered Rayleigh numbers between 4850 and 54,800 and aspect ratio of approximately 40. Secondary cells were noted at Ra as low as 6228. Interferometry showed that most of the temperature drop exists in boundary layers near the walls. The core is well mixed and of relatively uniform temperature with little or no vertical stratification. [Reprinted with permission from Elsevier. Copyright, 2005].
