Flow pattern and agglomeration in the dust outlet of a gas cyclone investigated by Phase Doppler Anemometry

Further, the measurements prove that due to the dust load there is a change in vortex from a potential vortex to a solid body vortex within the downcomer tube. While the effect of particles on velocity and the associated deceleration of the vortex was well-known in the literature, the change of vortex type had not been observed before.
