Abstract

The CFD-DPM (computational fluid dynamics-discrete particle model) and the response surface methodology has been performed to optimize the geometrical ratios of cyclone separator. The research results illustrate that the most significant geometrical parameter is the vortex finder diameter. Other four factors have significant effects on the cyclone performance viz.

the inlet width

inlet height

the cyclone total height

and the vortex finder length. In addition

there were strong interactions between the effect of the inlet width and inlet height

inlet dimensions and the vortex finder diameter on the pressure drop. There were strong interactions between the effect of the vortex finder diameter and inlet height

the vortex finder length and the cyclone total height on the separation efficiency. Finally

a new set of geometrical ratios was obtained to achieve minimum pressure drop and maximum separation efficiency. When the value of

was 0.40

0.26

0.34

6.28

0.66

respectively

the minimum pressure drop was 2.32kPa and the maximum separation efficiency was

99.27%.
