摘要 采用拉格朗日离散相模型(DPM)模拟固相颗粒的轨迹,研究了不同速度对不同粒径的颗粒分离效果的影响以及进口位置与分离效率的关系,结果表明速度对小粒径颗粒的分离效率影响较小,当速度大于15 m/s时,增大速度对大粒径颗粒的分离效率没有明显效果。从进口上端进入的气流其分离效率最小。 The trajectory of particles was solved by using Lagrangian discrete phase model, and effect of different velocities on separate efficiency for different particles and the relationsh/p between injection position and separate efficiency was studied. The results showed that the effect on small particles was small, and it was not visible when velocity was more than 15 m/s. The injection position was also very important for separate efficiency. It has the smallest separate efficiency from the upper inlet.
