Numerical analysis of flow characteristics and
separation efficiency in a highefficiency cyclone has been performed.
Several models based on the experimental observation for a design
purpose were proposed. However, the model is only estimated the
cyclone&039;s performance under the limited environments; it is difficult to
obtain a general model for all types of cyclones. The purpose of this
study is to find out the flow characteristics and separation efficiency
numerically. The Reynolds stress model (RSM) was employed instead
of a standard kε or a kω model which was suitable for isotropic
turbulence and it could predict the pressure drop and the Rankine
vortex very well. For small particles, there were three significant
components (entrance of vortex finder, cone, and dust collector) for
the particle separation. In the present work, the particle reentraining
phenomenon from the dust collector to the cyclone body was observed
after considerable time. This reentrainment degraded the separation
efficiency and was one of the significant factors for the separation
efficiency of the cyclone.
