COLLEGE PARK, Md. – If you think your origami skills can’t be beat – try this: (1) use the world’s thinnest material, (2) make the origami fold and unfold itself, and (3) pack into your miniscule orig...
水泵转速变化对进出水流道水力损失的影响（Influence of Rotational Speed of Pumps on Hydraulic Losses in Suction Boxes and Discharge Passages）
水泵 转速 水力损失 进出水流道

在比较各种进出水流道水力损失研究方法的基础上，运用计算流体动力学方法数值模拟了4种水泵装置内部流动，研究水泵转速变化对进出水流道水力损失的影响。数值计算结果表明，由于水泵装置中进水流道内部流动受水泵叶轮旋转引起的水流预旋的影响，因而小于无泵单独运行时的水力损失。水泵转速变化后，在相同流量下，进水流道的水力损失基本不变。水泵导叶出口水流条件和剩余环量影响出水流道的水力特性，水力损失随流量变化的关系非...
