physical and computational fluid dynamics models have been developed
to describe the rotating zigzag bed (RZB). The pressure distribution
in a RZB was investigated first. It was found that the simulations
agreed well with experiments, so the reliability of the models was
proved. The simulations suggest that the pressure drop decreases with
the rotating bed thickness (*H*, the height between
the rotating and stationary disks) within certain limits, particularly
under a high gas flow rate. Also, the dead zones in the flow field
are obviously reduced when we enlarge the rotor in the radial dimension.
The optimal rotating bed thickness of 96 mm obtained by the principle
of equal area was verified in the simulations. So, the principle can
be used in the structural design of a RZB.
