摘要

分析了提高流体转速的效果。导出了朗肯涡旋的伯努利方程和涡度方程,并描述了匹配解的方法。解释了强制旋转流动的情况,并介绍了分岔,水力跳跃以及稳定和不稳定行为之间的转换。对比了汉斯·贝特和爱德华·泰勒的伦理学观点。其他主题包括围绕圆柱体和球体的潜在流动以及可以学习的关于波浪河床流动的经验教训。

Intermezzo: Effects of Increasing Reynolds Number
Effects of increasing fluid speed are analyzed. The Bernouilli and vorticity equations are derived, and the method of matching solutions is described for the Rankine vortex. Cases in which rotational flow is mandatory are explained, and bifurcations, hydraulic jumps, and transitions between stable and unstable behaviors are introduced. The ethical views of Hans Bethe and Edward Teller are contrasted. Other topics include potential flow around both cylinders and spheres and lessons that can be learnt about flow over a wavy streambed.
