Vibrations and vortices in combustion chambers

Computational and experimental studies have been made of large-scale vortex structures as sources of acoustic vibrations. Low-frequency sources of vibration in combustion chambers of solid propellant jet engines have been shown to be due to the hydrodynamic instability of large-scale vortex structures in the main gas flow.M.
