排气管偏置分离器分离性能的数值模拟
Numerical simulation of separation performance in cyclone with excentric vent pipe
摘要
Abstract
The Reynolds stress model ( RSM ) was used to predict the gas flow of two cyclones with different vent pipe locations, and particle paths were calculated with the stochastic Lagrangian model.The calculated gas flow field was in reasonable agreement with experiment data. The numerical simulation results indicated that when the vent pipe was excentric, the cyclone obtained greater tangential velocity around the vent pipe, smaller shortcut flow, stronger trend of particles' centrifugal motion and almost unchanged pressure drop of the cyclone, which resulted in higher collection efficiency and better economical efficiency.关键词
