DESCRIPTION:A cyclone separator is a flow device used to separate particle
 s from a fluid by centrifugal forces in a rapidly swirling flow.  They are
  very effective because they do not use filters. Cyclones are known to gen
 erate narrow-band noise centred around one or more distinct frequencies. W
 e will refer to the noise as a cyclone hum. This hum is hypothesised to be
  a result of oscillations of the vortex core. For small cyclones this hum 
 presents as unwanted noise\, however in larger industrial units\, the osci
 llations can lead to structural damage. In this talk we will see how the o
 scillations are produced\, how it leads to noise and what we could be done
  to suppress the oscillations. The method of examining the oscillations co
 uld be applied to other swirling systems like the flow within combustion c
 hambers.
