An experimental study of starting plumes over area sources
TL;DRAbstract
Experiments have been performed to study the dynamics of plumes which develop, if buoyant fluid enters a homogeneous, unstratified environment through a source of finite width. The experiments were conducted in a cubic tank of salt water with 0.8m side length into which dyed fresh water was released at a constant volume-flow rate through a circular felt at the bottom. The governing \nnon-dimensional parameter of the flow, namely the ratio of inflow velocity to buoyancy velocity, was varied over more than two orders of magnitude in the experiments. The flow is shown to pass through two distinct phases, and a new \nintegral model is presented which describes the flow in the early stage. For later times and at larger distances from the source, the flow is found to be well described by Turner’s model for starting plumes from point sources.
