| Abstract: | The gas flow fields of cyclones are simulated by using Reynolds Stress Transformation Model(RSTM).Based on this,separation efficiencies and pressure drops of these cyclones are studied,separation performances with different temperature and pressure were presented,and the predicted separation performances were compared with the experimental data.The results indicate that pressure drops and separation efficiencies are decreased at high temperature,and the temperature has an important effect on the fine partic... |
