The Use of Centre Bodies and De-Swirl Vanes in the Exhaust of Cyclone Dust Separators

This study arises from vibration problems that have been encountered in cyclones operated at high pressure. Work has shown that such vibrations can be triggered by the complex flow process and regular fluid dynamic periodicities that can occur especially in the exhaust nozzle. One such phenomenon is...

Description
Summary:This study arises from vibration problems that have been encountered in cyclones operated at high pressure. Work has shown that such vibrations can be triggered by the complex flow process and regular fluid dynamic periodicities that can occur especially in the exhaust nozzle. One such phenomenon is the precessing vortex core (PVC); this is where the central forced vortex region of the flow precesses about the central axis of the system.
