Definition

quotient of gravitational forces and thermodiffusion forces for heat transfer in forced convection of fluids, expressed by

$F r * = \frac{g l^{3}}{α^{2}}$ ; where

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

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

$α$ :: is thermal diffusivity (ISO 80000-5: Thermodynamics)

quotient des forces de gravitation par les forces de thermodiffusion pour le transfert de chaleur en convection forcée de fluides, exprimé par:

$F r * = \frac{g l^{3}}{α^{2}}$ ; 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

$α$ :: est la diffusivité thermique (ISO 80000-5: Thermodynamics)
