Effects of driving load and pipe diameter on flow characteristic of two-phase boiling water

  • 摘要: 利用地面转台旋转产生的离心力模拟飞行过载,并在此过载作用下进行了不同管径内沸水两相流实验.通过改变过载大小、管径、沸水流量等参数,得到沸水流动特性的初步变化规律,并对顺载作用下沸水的流型进行了拍摄.结果显示顺载和管径对沸水的流动会产生明显的影响.顺载作用使管内出现了一些新流型,并且增加了流动的不稳定性.压差随顺载的增大而减小,且管径越大其减小的程度越大.实验结果增加了动载下管道内工质流动特性的数据积累,同时对飞行器上蒸发循环制冷系统的理论分析和设计提供一定的借鉴和参考.
