1) parallel vertical rifled tubes
垂直并联内螺纹管
1.
In the light of hydrodynamic characteristics of waterwall tubes of 600 MW supercritical circulating fluidized bed(CFB) boilers at low mass flow rate, experimental studies were carried out on instability of two-phase flow in parallel vertical rifled tubes.
针对600 MW超临界循环流化床(CFB)锅炉水冷壁管在低质量流速条件下的水动力特性,进行了垂直并联内螺纹管内两相流不稳定性的试验研究,得到了不同条件下的水动力特性曲线和压力降、密度波2种脉动的典型脉动曲线。
2) vertical rifled tube platen
垂直内螺纹管管屏
3) vertical rifled waterwall
垂直内螺纹管水冷壁
4) parallel inclined rifled tube
倾斜并联内螺纹管
5) Parallel inclined inner ribbed pipe
并联倾斜内螺纹管
补充资料：垂直
当两直线所成的角为直角时，称它们互相垂直。这一概念也可推广到两平面间或直线与平面间的情况。
