摘要
通过数值模拟研究了超音速分离器内的流场特性与颗粒运动轨迹及液膜流动特性,分析了旋流强度和液滴直径对分离效率与液膜流量的影响。结果表明,增加旋流强度或液滴直径均可以提高分离效率与液膜流量。旋流强度为0.51时,0.1μm以下的液滴分离效率不超过30%。对于直径不大于0.1μm的液滴,最大分离效率仅为60.90%。
The flow field characteristics,particle trajectory and liquid film flow characteristics in the supersonic separator were studied by numerical simulation,and the effects of cyclonic flow intensity and droplet diameter on the separation efficiency and liquid film flow rate were analyzed.The results showed that increasing the cyclonic strength or droplet diameter could improve the separation efficiency and liquid film flow rate.The separation efficiency of droplets below 0.1µm does not exceed 30%when the cyclonic intensity is 0.51.For droplets with diameters not larger than 0.1µm,the maximum separation efficiency was only 60.90%.
