| 摘 要： | 以空气和水为工质，在40mm×1.6mm的窄矩形通道内对竖直状态和摇摆状态下两相流流型进行了研究。流型由拍摄照片辨别，实验通道内观察到的流型有泡状流、弹状流、搅混流和环状流，绘制出窄矩形通道内的流型图，并与常规尺寸圆管内两相流型进行了对比。摇摆对窄矩形通道内流型的影响与常规尺寸圆管相似，但由于狭小空间的限制及表面张力的作用，摇摆对两相流动并无明显影响。

| Abstract: | The two-phase flow patterns of air-water mixture were studied in a narrow rectangular channel (40 mm×1.6 mm) in rolling and steady condition, respectively. The flow patterns were observed by using a CCD camera and were identified by examining the video images, and can be classified into bubbly flow, slug flow, churn flow and annular flow. The flow patterns were compared with the large diameter round tube, and the flow pattern maps were given. The effect of rolling on flow pattern in narrow rectangular channel is similar to that in the large diameter round tube, but due to the small room and surface tension effect. |
