无上排气芯管旋风分离器的性能预测

Performance Prediction of a Cyclone Separator without an Upper Exhaust Core Pipe

对一种无上排气芯管旋风分离器进行了性能预测，在非正交的贴体坐标系下，用非交错的ＳＩＭＰＬＥ算法对其内部气相场进行数值模拟。在拉格朗日坐标系下，用随机轨道法跟踪颗粒的轨迹。计算得到了分离器的分级效率和阻力系数，并和实验结果进行了比较。

A performance prediction is conducted of a cyclone separator without an upper exhaust core pipe.Under a non orthogonal adhesion body coordinate system a numerical simulation of an internal gas phase field has been performed with the help of a non intersecting SIMPLE algorithm.Under a Lagrange coordinate system the trajectory of particles was tracked by the use of a random orbital method.Through calculations the classification efficiency and resistance coefficient of the separator were obtained with these results being compared with experimental ones.
