Abstract
The investigation concerns the experimental simulation of the behaviou r of a turbulent plume penetrating a stratified medium. The simulation is isothermal and uses an helium-air mixed jet evolving in a cavity r eproducing the stratified area. The results concern the evolution of t he spectrum and the characteristic scales of the turbulent structures as the flow crosses the interface.
