The effect of the particle mass loading (1.6–115.3 g/m³) on the performances of a cyclone separator is studied by two-way coupling CFD simulation and experiments. The increasing of the particle mass loading enriches the particles at the wall region. At lower inlet air velocity, the separation efficiency increases with the increasing of the particle mass loading due to the larger particle sweeping effects and the aggregation of smaller particles. The full elastic particle–wall collision and the perfect dust box bottom collection assumptions cause CFD simulation overpredicting the separation efficiency of smaller particles. A partial elastic particle–wall collision assumption overcame the problem and reduced the calculated separation efficiency. Our CFD simulation can reasonably predict the separation efficiency at different particle mass loadings.

颗粒质量负荷的影响（1.6-115.3 g / m ³通过双向耦合CFD仿真和实验研究了旋风分离器的性能）。颗粒质量负荷的增加使壁区域处的颗粒富集。在较低的进气速度下，由于较大的颗粒吹扫作用和较小的颗粒聚集，分离效率随颗粒质量负荷的增加而增加。完全的弹性粒子-壁碰撞和理想的集尘箱底部收集假设导致CFD模拟过高地预测了较小粒子的分离效率。部分弹性粒子-壁碰撞假设克服了这个问题，并降低了计算的分离效率。我们的CFD模拟可以合理地预测不同颗粒质量负载下的分离效率。
