Definition

quotient of viscous force and capillary force acting across an interface between a liquid and a gas, or between two immiscible liquids for a flow of fluid influenced by interfacial tension, expressed by

$C a * = η v / γ$ ; where

$η$ :: is dynamic viscosity (ISO 80000-4: Mechanics) of the fluid,

$v$ :: is characteristic speed (ISO 80000-3: Space and time), and

$γ$ :: is surface or interfacial tension (ISO 80000-4: Mechanics)

quotient de la force visqueuse par la force capillaire agissant au niveau d'une interface entre un liquide et un gaz, ou entre deux liquides non miscibles, dans le contexte de l'écoulement d'un fluide influencé par la tension interfaciale, exprimé par:

$C a * = η v / γ$ ; où

$η$ :: est la viscosité dynamique (ISO 80000-4: Mechanics) du fluide;

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

$γ$ :: est la tension superficielle ou interfaciale (ISO 80000-4: Mechanics)

Notes

The dynamic capillary number is also given by the quotient of the Weber number and the Reynolds number.

Le nombre capillaire dynamique est également donné par le quotient du nombre de Weber par le nombre de Reynolds.
