摘　　要：对旋进旋涡流量计中旋涡发生体的结构进行了如下改进:将旋涡发生体的叶片与主轴的夹角由原来的60°减小到45,°将叶片由六片增加到七片。利用FLUENT数值仿真软件对改进后的旋进旋涡流量计做了数值仿真计算,对改进方案进行了验证,最后在实验装置上进行了试验。仿真结果与试验结果均表明,改进后的旋进旋涡流量计压力损失有了较大幅度的减小,并且在保证压力损失较小的同时其测量下限也有所降低,克服了旋进旋涡流量计应用中的一个不足。The structure of swirler in swirlmeter is changed . The corner dimension between inlet blades and basic shaft is changed into 45 from 60 and inlet blades into seven from six. Improved swirlmeter is simulated with FLUENT at first, then it is examined on testing equipment. Both simulation and experiment show＇that the pressure loss of swirlmeter is reduced and at the same time the lowest limit of swirlmeter get lower by changing the structure of swirler. As a result, one of fault of swirlmeter is solved.
