Abstract
A model for turbulent natural convection based on the cyclic destruction and rebuilding of the boundary layer has been proposed by Howard [6]. A close look at more recent experimental data shows that the boundary layer is probably not destroyed as Howard postulated, but is stable with thermals growing upon it and producing the periodicity of the phenomenon. A modified model is proposed.Keywords
