Record 1 2004-10-26

English

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

Scalar function ([phi]) which always exists in irrotational fluid motion and is defined by the equation: V = -[nabla phi], where V is the velocity vector.

OBS

The equation implies that V is normal to the equipotential lines and is directed from high to low potential.

French

Domaine(s)
  • Physique de l'atmosphère
  • Mécanique des fluides et hydraulique (Physique)
DEF

Fonction scalaire([phi]) qui existe toujours dans le mouvement irrotationnel d’un fluide et est définie par l'équation : V=-[nabla phi], où V est le vecteur vitesse.

OBS

L’équation implique que V est normal aux lignes équipotentielles et est dirigé des hauts potentiels vers les bas.

Spanish

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

Función escalar [phi] que siempre existe en un fluido en movimiento irrotacional [...]

OBS

La ecuación implica que V es perpendicular a las líneas equipotenciales y está dirigida de los valores altos a los bajos.
