摘要 以石油工业为背景的油水流动是典型的液液两相流。管道中的两相流动研究的主要内容是充分发展之后的流型和压降等。此文通过实验研究了一种非稳态阶段的两相流动—经过导流片之后一段距离之内的两相旋涡流动。实验划分了不同相含率与表观流速下的流动形态,研究了导流片前后的压降规律。 The oil-water flow with the background of petroleum industry is the typical Liquid-Liquid two-phase flow. The most previous works is the study of the full developed flow： the flow pattern, pressure drop and so on. In contrast, in this work a experiment sturdy was done about no-stable two-phase flow-The two phase swirl flow black of the conductor vane. Four flow patterns under different kinds of oil volume fraction and surface flow velocity were divided.
