摘　　要：采用Fluent软件数值模拟了新型油-水-气三相旋流器的分离性能,并以分离效率为目标函数对气-液分离腔主要尺寸进行了优化设计。结果表明,该型油-水-气三相旋流器在油滴与气泡直径为50μm时具有最优的分离效率,且其气泡迁移效率较油滴迁移效率高.当气泡直径为50μm时,气-液分离效率达到99%以上;当气泡直径小于40μm时,气-液分离效率随直径的减小显著下降;当气泡直径小于10μm时,气-液分离效率趋近于零.经对比分析建立了溢流口直径与分流比的线性关系式,且得到优选后气-液分离腔最优主要结构尺寸:分离腔长度203mm,分离腔直径60mm,溢流口插入长度20mm.The Fluent was adopted to simulate the separation performance of the new oil-water-gas cy-clone ,and the separation efficiency was regarded as a objective function to optimally design the main si-zes of the gas-liquid separation chamber .The results show that the separation performance of the oil-gas-water cyclone is best when the diameters of oil droplets and bubbles are 50um ,and the migration efficiency of bubbles is better than that of oil droplets .The gas-liquid separation efficiency is over 99%when the bubble size is 50um ;the gas-liquid separation efficiency decreases obviously with the bubble diameters reducing w hen the bubble size is less than 40um ;the gas-liquid separation efficiency approa-ches to zero when the bubble size is less than 10um .Through the comparative analysis ,the linear rela-tion betw een the diameter of overflow and the split ratio w as established ,and the optimum sizes of the main structure of the gas-liquid separation chamber are 203mm of length ,60mm of diameter and 20mm of insert length .
