Numerical Simulation of the Influence of Outer Chamber Height on Flow Field in Circumfluent Cyclone Separator

摘要

Through the numerical simulation method, the Reynolds stress turbulence model (RSM) was used to simulate the flow field of circumfluent cyclone separator with three different outer chamber heights. Three circumfluent cyclones (CFC), with different outer chamber heights, are compared with each other. Pressure fields, velocity fields and pressure drop have been investigated. The results show that in a certain range, the outer chamber height of circumfluent cyclone separator has an optimum value, which can have higher separate efficiency and lower pressure drop. This provides a strong theoretical basis for the local optimization design of the cyclone.
