Reynolds finds that turbulence begins when r exceeds about 2000 . 雷诺发现当雷诺数大于约2000时开始产生湍流。
If the reynolds number is large the flow is no longer laminar as the particles tend to move in a random manner . 如果雷诺数很大,由于流体质点变成杂乱无章的运动流动不再是层流。
The linear scaling and the reynolds number represent classical, aerodynamic similitude requirements applicable to law-speed flight . 线性缩尺和雷诺数是低速飞行时经典的气动力模似要求。
