Supersonic steam jet in subcooled water in the range of 20~60℃was investigated experimentally and velocity distribution for the tail of supersonic steam jet was obtained.
针对超音速汽流在20~60℃过冷水中浸没射流进行实验研究,得到射流尾部的速度分布规律。
Under floor pattern of submerged bottom floor,the velocity distributions in the submerged jet region and attaching wall jet region of stilling basin are analyzed by the jet hydraulic theory,and the velocity distribution formulas are drawn.
并对淹没底流流态下,消力池内的淹没射流区、附壁射流区内的流速分布采用射流力学理论进行了分析,得出了其流速分布公式。
The flow form of dual impeller and the velocity distribution near the impeller depend highly on the interlayer spacing.
对双层搅拌桨体系,不同层间距下宏观流动形态不一样。 上层桨与下层桨叶轮区、循环区速度分布与层间距密切相关。
It is shown that the velocity distribution of sediment-laden flow obeys the exponential or logarithmic law in the zone far away from the bottom outlet.
本文研究结果还表明,在距排沙底孔较远的孔口影响域以外的区域,挟沙水流流速在水深方向上成对数或指数分布;而在孔口影响域内,挟沙水流流速分布不同于单相水流的对数或指数流速分布规律。
