The mechanism of fluidization has been investigated, in
particular the method of initiation of movement. A detailed study
of the discontinuities found in many liquid fluidized systems has
been made. By means of an artificially created discontinuity or
parvoid the mechanism of propagation of these parvoids has been
studied and a correlation produced which agrees with the data obtained
from the naturally occurring parvoids up to a superficial water velocity
of 1.5 Umf. At higher superficial velocities the curve relating water
velocity to parvoid velocity passed through a series of peaks or breaks.
These can be explained on the basis of an inherent mechanism of speed
control by means of reductions in the amount of dense phase existing
between successive parvoids.
