eddy viscosity [4 records]

Record 1 2002-04-23

English

Subject field(s)
  • Meteorology
  • Fluid Mechanics and Hydraulics (Physics)
DEF

The virtual viscosity resulting from the interaction of eddies within a turbulent flow.

OBS

eddy viscosity ... These eddies effect an exchange of momentum between adjacent layers in a manner similar to, but on a far larger scale than, the exchange of molecules in molecular viscosity.

French

Domaine(s)
  • Météorologie
  • Mécanique des fluides et hydraulique (Physique)
DEF

Viscosité virtuelle résultant de l'interaction des tourbillons de turbulence dans un flux turbulent.

OBS

viscosité turbulente [...] Ces tourbillons amènent un échange de quantité de mouvement entre les couches adjacentes d'une manière analogue, mais à beaucoup plus grande échelle, à celle de l'échange des molécules dans la viscosité moléculaire.

Spanish

Campo(s) temático(s)
  • Meteorología
  • Mecánica de fluidos e hidráulica (Física)
DEF

Viscosidad virtual debida a la interacción entre los remolinos en una corriente turbulenta.

OBS

viscosidad de la turbulencia: [...] Estos remolinos realizan un intercambio de cantidad de movimiento entre capas adyacentes de una manera semejante al intercambio de moléculas en el caso de la viscosidad molecular, pero en una escala mucho mayor.

Record 4 1979-01-23

English

Subject field(s)
  • Hydrology and Hydrography
OBS

The numerical value of the eddy viscosity depends upon the size and intensity of the eddies (...)

French

Domaine(s)
  • Hydrologie et hydrographie
OBS

La viscosité tourbillonnaire est donc l'expression d'un transfert de forces d'impulsion d'un mouvement moyen.
