Numerical Study of Gas-liquid Micro-cyclone Separator Flow Field

摘要

Based on Reynolds stress model (RSM), the three-dimensional flow field of a gas-liquid micro-cyclone separator with a diameter of 75 mm have been simulated with the computational fluid dynamics (CFD). The distribution of gas tangential velocity of the inside flow field and its effects on the movement of liquid droplets are presented in this paper. The results suggest that the micro-cyclone accords with the vortex motion rules and the droplets fractional efficiency change with the inlet flow rate. Also, an efficient separation zone of the micro-cyclone have been found.
