We experimentally investigate the behaviour of a line-source plume falling through a finite two-layer stratified ambient where the depth of the upper ambient layer increases in time. Laboratory observations suggest one of two possible flow regimes depending on the value of ๐ , which represents the relative loss of buoyancy experienced by the plume upon crossing the ambient interface. When ๐>1 , a classical filling-box-type flow is realized and plume fluid always reaches the bottom boundary. By contrast, when ๐tt . The significance of our findings is discussed in the context of the ventilation of natural and hybrid ventilated buildings and of effluent discharge through marine outfall diffusers.
