MECHANISM FOR TRANSITION TO TURBULENCE IN BUOYANT PLUME FLOW.

This paper reports a theorectical and experimental study of the fundamental mechanism responsible for transition in natural convection plume flow. Theoretically, it is argued that the transtion occurs when the time of viscous penetration normal to the plume becomes comparable with the minimum time period with which the plume can fluctuate as an unstable inviscid stream. It is also argued that at transition the plume wavelength must always scale with the local plume diameter.
