本文介绍了在高压水回路试验装置上进行的亚临界压力下两种内螺纹管和光管的阻力特性试验;通过试验得出了相应的单相阻力系数、两相流与全液相流的摩擦压降倍率以及与含汽率之间的关系曲线
In this paper, the resistance characteristics of two kinds of female-threaded tubes and light pipes under subcritical pressure are introduced in the high-pressure water circuit test device. The corresponding single-phase resistance coefficient, the friction between two-phase flow and the whole liquid flow Pressure drop rate and the relationship between the rate of steam curve
