基于 CFD -PBM积分矩量法旋风分离器中颗粒聚团的数值模拟
Numericle Simulation of Particle Aggregation in Cyclone Separator Using Quadrature Method of Moments in CFD-PBM
摘要
Abstract
In order to get the particle agglomeration effect on the separation performanceof Cyclone separator under different in-let particle concentration to speed research on its impact on efficiency.Based on the Reynolds stress model (RSM)calculation of turbulent flow through the population balance model (PBM)coupled CFD numerical calculation of particle phase.Results showed that:at the time of 2 s,aggregation role within the cyclone has stabilised,the particle size in the range of 1.5 μm to 3 μm basic set cannot be arrested within the particles in cyclone separator and particle size greater than 5 μm the separation efficiency is close to 100%;with increasing inlet mass concentration,the overall separation efficiency increase,and increase the inlet gas veloc-ity,the impact on the separation efficiency is not great.关键词
