摘　　要：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38mm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 drop size and drop velocity have important research value. The experiment a 38 mm inner diameter standard pulse sieve column. The study based on was set as the continuous phase, while the pure kerosene as the dispersed on with a dual optical probe technology to explore the influence of opera disperse on dispe d phase superficial velocity, continuous phase rsed drop size. In the experiment, a measure column, dispersed was carried out in two-phase ： water phase. They went tion data, such as superficial velocity and pulse intensity ment 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.
