High-Enthalpy High-Speed Cavity Flow

The cavity, or cavern, is often encountered on aircraft surfaces or in apparatus channels. Recent interest in the study of cavities was due to the fact that cavities are often used to exert control over complex flows at supersonic speeds, for instance, at boundary layer bleed or as flame holders.

Results of an experimental and numerical study of supersonic turbulent high-enthalpy flow in a channel with cavity are reported.

High-Enthalpy High-Speed Cavity Flow

On the basis of wind-tunnel tests performed in the IT-302M short duration wind tunnel, data on the flow structure and on the disribution of static pressure along the model walls were obtained. These data were subsequently used to verify the numerical algorithm. In the calculations, a parametric

study of the effects of Mach number, cavity configuration, and temperature factor on flow quantities was performed. It was numerically shown that variation of the above parameters leads to a transition of the flow regimes in the vicinity of the cavity.
