G o

Definition

characterization of the stability of laminar boundary layer flows in transfer of matter in a boundary layer on curved surfaces, expressed by

$G o = \frac{v l_{b}}{v} \sqrt{(\frac{l_{b}}{r_{c}})}$ ; where

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

$l_{b}$ :: is boundary layer thickness (ISO 80000-3: Space and time),

$v$ :: is kinematic viscosity (ISO 80000-4: Mechanics), and

$r_{c}$ :: is radius of curvature (ISO 80000-3: Space and time)

caractérisation de la stabilité des écoulements de couches limites laminaires dans le contexte du transfert de matière dans une couche limite sur des surfaces courbes, exprimée par:

$G o = \frac{v l_{b}}{v} \sqrt{(\frac{l_{b}}{r_{c}})}$ ; où

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

$l_{b}$ :: est l'épaisseur (ISO 80000-3: Space and time) de la couche limite;

$v$ :: est la viscosité cinématique (ISO 80000-4: Mechanics); et

$r_{c}$ :: est le rayon de courbure (ISO 80000-3: Space and time)

Notes

The Goertler number represents the ratio of centrifugal effects to viscous effects.

Le nombre de Goertler représente le rapport des effets centrifuges aux effets visqueux.
