作为设计脉冲筛板柱的重要水力学特性参数，分散相液滴尺寸和液滴速率有重要的研究价值。使用内径为38 mm的标准脉冲筛板柱，以水为连续相，纯煤油为分散相，利用光纤双探针法测量分散相表观流速、连续相表观流速和脉冲强度等因素对分散相液滴尺寸的影响。结果表明，光纤两相流参数测量系统能够很好地识别液液两相中的不同相，验证了光纤探针法应用于液液两相流的可行性。

For the important hydraulic parameters to design pulsed sieve column,dispersed drop size and drop velocity have important research value.The experiment was carried out in a 38 mm inner diameter standard pulse sieve column.The study based on two-phase:water was set as the continuous phase,while the pure kerosene as the dispersed phase.They went on with a dual optical probe technology to explore the influence of operation data,such as dispersed phase superficial velocity,continuous phase superficial velocity and pulse intensity on dispersed drop size.In the experiment,a measurement system for two-phase flow could recognize water and kerosene well in the liquid-liquid two-phase flow.Experimental results prove the feasibility of the application of optical probe technology to the liquid-liquid two-phase flow.
