本文提出了一种计算流体动力学方法来预测和评价温度、操作压力和入口速度对气体旋风分离器收集效率的影响。利用电子表格和商用CFD代码FLUENT 6.0进行数值求解。本文还综述了四种预测气旋收集效率的经验模型，即Lapple[1]、Koch and light[2]、Li and Wang[3]和Iozia and Leith[4]。通过与实验数据的比较，所有的预测结果都是令人满意的。CFD模拟预测了所有工况下的气旋截止尺寸，与实验数据的偏差为3.7%。具体而言，计算机模拟的结果表明，CFD模型是模拟旋风收集效率的最佳方法。
This work presents a Computational Fluid Dynamics calculation to predict and to evaluate the effects of temperature, operating pressure and inlet velocity on the collection efficiency of gas cyclones. The numerical solutions were carried out using spreadsheet and commercial CFD code FLUENT 6.0. This paper also reviews four empirical models for the prediction of cyclone collection efficiency, namely Lapple [1], Koch and Licht [2], Li and Wang [3], and Iozia and Leith [4]. All the predictions proved to be satisfactory when compared with the presented experimental data. The CFD simulations predict the cyclone cut-off size for all operating conditions with a deviation of 3.7% from the experimental data. Specifically, results obtained from the computer modelling exercise have demonstrated that CFD model is the best method of modelling the cyclones collection efficiency.
