R e e

Definition

relation between the speed of an object submerged in water relative to the water, and wave propagation speed, expressed by

$R e e = \sqrt{g l} / v$ ; where

$g$ :: is acceleration of free fall (ISO 80000-3: Space and time),

$l$ :: is characteristic length (ISO 80000-3: Space and time), and

$v$ :: is speed (ISO 80000-3: Space and time) of the object relative to the water

relation entre la vitesse d'un objet immergé dans l'eau par rapport à l'eau, et la vitesse de propagation des vagues, exprimée par:

$R e e = \sqrt{g l} / v$ ; où

$g$ :: est l'accélération due à la pesanteur (ISO 80000-3: Space and time);

$l$ :: est la longueur caractéristique (ISO 80000-3: Space and time); et

$v$ :: est la vitesse (ISO 80000-3: Space and time) de l'objet par rapport à l'eau

Notes

The Reech number can be used to determine the resistance of a partially submerged object (e.g. a ship) of length $l$ (in direction of the motion) moving through water.

A similar quantity is defined as the Boussinesq number $B s = v / \sqrt{2 g l}$ .

Le nombre de Reech peut être utilisé pour déterminer la résistance d'un objet partiellement immergé (par exemple un navire) de longueur $l$ (dans la direction du déplacement) se déplaçant dans l'eau.

Une grandeur similaire est définie en tant que nombre de Boussinesq $B s = v / \sqrt{2 g l}$ .
