N e

Definition

relation between convective current and diffusive current of ions in electrochemistry, expressed by

$N e = v l / D *$ ; where

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

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

$D * = (D^{+} + D^{-}) / 2$ ; where::

$D^{+}$ , $D^{-}$ ::: are diffusion coefficients (ISO 80000-9: Physical chemistry and molecular physics) of positive or negative ions respectively

relation entre le courant de convection et le courant de diffusion des ions en électrochimie, exprimée par

$N e = v l / D *$ ; où

$v$ :: est la vitesse (ISO 80000-3: Space and time),

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

$D * = (D^{+} + D^{-}) / 2$ ; où::

$D^{+}$ , $D^{-}$ ::: sont les coefficients de diffusion (ISO 80000-9: Physical chemistry and molecular physics) des ions positifs ou négatifs respectivement

Notes

This number is also called electric Nusselt number.

Sometimes this quantity is called the Reynolds electric number.

Ce nombre est aussi appelé nombre électrique de Nusselt.

Parfois, cette grandeur est appelée nombre de Reynolds électrique.
