Paper Abstract

In the present study, we develop a simple mathematical model of the vapour jets flow inside a cavity, in order to provide some understanding of the physics of the flow and to obtain qualitative data relative to the vapour flow properties. We consider a fluid as an ideal gas (air) at high pressure and temperature injected from orifices located perpendicularly to the free stream of a cavity with a simplified geometry. The jets injected are assumed to be at transonic (supersonic) and turbulent regimes.
