Definition

special case of the Nusselt number for heat transfer (item Nusselt number <heat transfer>) in case of conductive heat transfer in a solid body, expressed by

$B i = K l / λ$ ; where

$K$ :: is coefficient of heat transfer (ISO 80000-5: Thermodynamics) through the surface,

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

$λ$ :: is thermal conductivity (ISO 80000-5: Thermodynamics) of the body

cas particulier du nombre de Nusselt pour transfert de chaleur (Nusselt number <heat transfer>) dans le cas d'un transfert de chaleur par conduction dans un corps solide, exprimé par:

$B i = K l / λ$ ; où

$K$ :: est le coefficient de transmission thermique (ISO 80000-5: Thermodynamics) à travers la surface;

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

$λ$ :: est la conductivité thermique (ISO 80000-5: Thermodynamics) du corps

Notes

The characteristic length is commonly defined as the volume of the body divided by its surface area.

La longueur caractéristique est généralement définie comme le rapport du volume du corps à l'aire de sa surface.
