  • The maximum tangential velocity in the cyclone decreases with increasing both the cyclone inlet width and height.
  • No acceleration occurs in the cyclone space (the maximum tangential velocity nearly constant throughout the cyclone). Also, the variation of both the static pressure and axial velocity in the axial direction is very limited.
  • Increasing the cyclone inlet width or height decreases the pressure drop at the cost of increasing the cut-off diameter. So an optimization procedure is needed to estimate the optimum value of inlet dimensions.
  • Wider inlet cyclones (b/D> gap between the cyclone barrel and the vortex finder are not preferred.
  • The effect of changing the inlet width on the cut-off diameter is more significant in comparison with that of the inlet height.
  • The optimum ratio of the inlet width to the inlet heightb/ais from 0.5 to 0.7.
