福禄数福禄数(Froude number,Fr)为流体力学中无量纲的纯量,为惯性力和重力效应之比,公式如下: 式中U为流体速度,L为物体特征长度,g为重力加速度。 明渠流和波浪力学中都常用到福禄数。在明渠流中,长度L为水深h。在波浪力学中,福禄数代表平均流速与重力波的波速之比。

Froude number 福禄数In continuum mechanics, the Froude number (Fr) is a dimensionless number defined as the ratio of the flow inertia to the external field (the latter in many applications simply due to gravity). Named after William Froude (/ˈfruːd/;), the Froude number is based on the speed–length ratio as defined by him, and is defined as: |
