摘　　要：摇摆产生的惯性力以及水平管路发生向上和向下倾斜,会使管道内两相流的流动型式发生变化。本文对直径25mm管内气-水两相流在摇摆周期为15s、摇摆角度为10°状态下的流型进行了实验,研究了气-水两相流在摇摆状态下的流动型式,并给出了流型图。实验结果表明,在一些气-水流量区域,两相流体在一个摇摆周期内存在两种流动型式。The flow pattern transition of two-phase flow is caused by the inertial force resulted from rolling and incline of horizontal tubes under rolling state. An experimental study on the flow patterns of gas-water flow was carried out in horizontal tubes under rolling state, which rolling period is 15 second and rolling angle is 10 degrees, and a pattern flow picture is shown. It was found that there are two flow patterns in one rolling period under some gas flux and water flux.
