S t

Definition

relation between heat transfer into a fluid from a surface and its heat transfer by convection, expressed by

$S t = K / (ρ v c_{p})$ ; where

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

$ρ$ :: is mass density (ISO 80000-4: Mechanics),

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

$c_{p}$ :: is specific heat capacity at constant pressure (ISO 80000-5: Thermodynamics) of the fluid

relation entre le transfert de chaleur dans un fluide par une surface et la chaleur transférée par convection, exprimé par:

$S t = K / (ρ v c_{p})$ ; où

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

$ρ$ :: est la masse volumique (ISO 80000-4: Mechanics);

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

$c_{p}$ :: est la capacité thermique massique à pression constante (ISO 80000-5: Thermodynamics) du fluide

Notes

The Stanton number is also given by

$S t = N u / (R e \cdot P r) = N u / P e$ ; where

$N u$ :: is Nusselt number for heat transfer (Nusselt number <heat transfer>),

$R e$ :: is the Reynolds number (Reynolds number),

$P r$ :: is the Prandtl number (Prandtl number), and

$P e$ :: is the Péclet number (Péclet number <heat transfer>).

Sometimes this quantity is called Margoulis number, symbol $M s$ or $M g$ .

Le nombre de Stanton est également donné par:

$S t = N u / (R e \cdot P r) = N u / P e$ ; où

$N u$ :: est le nombre de Nusselt pour le transfert de chaleur (Nusselt number <heat transfer>);

$R e$ :: est le nombre de Reynolds (Reynolds number);

$P r$ :: est le nombre de Prandtl (Prandtl number); et

$P e$ :: est le nombre de Péclet (Péclet number <heat transfer>).

Parfois, cette grandeur est appelée nombre de Margoulis, symbole $M s$ ou $M g$ .
