Reynolds number

雷诺数

Reynolds number

在流体力学中,雷诺数是一个无量纲的数量,用于帮助预测不同流体流动情况下的相似流动模式。 这个概念由乔治·加布里埃尔·斯托克斯(George Gabriel Stokes)于1851年提出,雷诺兹号是以奥斯本雷诺兹(Osborne Reynolds)命名的,他在1883年推广其使用。雷诺数定义为惯性力与粘性力的比例,从而量化了这些 给定流量条件的两种类型的力。 当执行流体动力学问题的缩放时,雷诺数常常出现,因此可用于确定两种不同流体流动情况之间的动态相似性。 它们也用于表征类似流体内的不同流动状态,例如层流或湍流:层流在低雷诺数下发生,其中粘性力是主要的,并且其特征在于平滑,恒定的流体运动; 湍流在高雷诺数下发生,并且由惯性力主导,倾向于产生混沌漩涡,涡流和其他流动不稳定性。 在实践中,匹配雷诺数并不足以保证相似性。 In fluid mechanics, the Reynolds number is a dimensionless quantity that is used to help predict similar flow patterns in different fluid flow situations. The concept was introduced by George Gabriel Stokes in 1851, but the Reynolds number is named after Osborne Reynolds, who popularized its use in 1883. The Reynolds number is defined as the ratio of inertial forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions. Reynolds numbers frequently arise when performing scaling of fluid dynamics problems, and as such can be used to determine dynamic similitude between two different cases of fluid flow. They are also used to characterize different flow regimes within a similar fluid, such as laminar or turbulent flow: laminar flow occurs at low Reynolds numbers, where viscous forces are dominant, and is characterized by smooth, constant fluid motion; turbulent flow occurs at high Reynolds numbers and is dominated by inertial forces, which tend to produce chaotic eddies, vortices and other flow instabilities. In practice, matching the Reynolds number is not on its own sufficient to guarantee similitude.

在英语 词典里Reynolds number的定义

字典中雷诺数的定义是一个无量纲数,vρl /η,其中v是流体速度,ρ是密度,η是粘度,l是系统的尺寸。 数字的值表示流体的流动类型。

The definition of Reynolds number in the dictionary is a dimensionless number, vρ l/η, where v is the fluid velocity, ρ the density, η the viscosity and l a dimension of the system. The value of the number indicates the type of fluid flow.
