Definition

relation between diffusive mass transfer within a given duration and mass storage rate in transient mass transfer, expressed by

$F o * = \frac{D t}{l^{2}}$ ; where

$D$ :: is diffusion coefficient (ISO 80000-9: Physical chemistry and molecular physics),

$t$ :: is duration (ISO 80000-3: Space and time) of observation, and

$l$ :: is length (ISO 80000-3: Space and time) of transfer

relation entre le transfert de masse par diffusion pendant une durée donnée et la vitesse de stockage de masse dans le contexte d'un transfert de masse transitoire, exprimée par:

$F o * = \frac{D t}{l^{2}}$ ; où

$D$ :: est le coefficient de diffusion (ISO 80000-9: Physical chemistry and molecular physics);

$t$ :: est la durée (ISO 80000-3: Space and time) d'observation; et

$l$ :: est la longueur (ISO 80000-3: Space and time) de transfert

Notes

The Fourier number for mass transfer is also given by

$F o * = F o / L e$ ; where

$F o$ :: is the Fourier number for heat transfer (Fourier number <heat transfer>), and

$L e$ :: is the Lewis number (Lewis number).

See also the Fourier number for heat transfer (Fourier number <heat transfer>).

Le nombre de Fourier pour le transfert de masse est également donné par:

$F o * = F o / L e$ ; où

$F o$ :: est le nombre de Fourier pour le transfert de chaleur (Fourier number <heat transfer>); et

$L e$ :: est le nombre de Lewis (Lewis number).

Voir aussi le nombre de Fourier pour le transfert de chaleur (Fourier number <heat transfer>).
