Buoyant convection from horizontal surfaces at const ant pressure
Published online by Cambridge University Press: 29 March 2006
Abstract
A two-dimensional horizontal flow is discussed, which is induced by other, buoyancy-driven flows elsewhere. It is an adaptation of the incompressible wall jet, which is driven by conditions a t the leading edge and has no streamwise pressure gradient. The relation of this flow to the classical buoyancy-driven boundary layers on inclined and horizontal surfaces is investigated, as well as its possible connexion with a two-dimensional buoyant plume driven by a line source of heat. Composite flows are constructed by patching various such solutions together. The composite flows exhibit $Gr^{\frac{1}{4}}$ scaling (Gr being the Grashof number).
