摘　　要：用高速动态分析仪对倾斜上升管中气液两相弹状流中Ｔａｙｌｏｒ气泡的运动速度进行了研究。获得了无干扰流场下Ｔａｙｌｏｒ气泡运动参数的测量结果，并分析了混合物流速及管倾角对气泡头部位置的影响，以及由此而引起的气泡漂移速度及液体速度影响系数的变化情况，在理论分析的基础上，推荐了计算气泡运动速度的实验关联式。并且与可利用的结果进行了比较，两者符合较好。An investigation was carried out for gas liquid slug flow in inclined tubes.The non invasive measurements of the gas liquid slug flow were taken by using the EKTAPRO 1000 High Speed Motion Analyzer.The Present paper has obtained the information on the velocity of the Taylor bubble and discussed the effect of the liquid velocity and the inclination angle on the position of bubble nose,which leads to the change of the drift velocity and coeffcient C 1.Based on the theoretical analysis,the correlation of the Taylor bubble velocity were obtained.The results are in good agreement with the available data.
