French translation for "von kármán constant"

constante de von kármán

Example Sentences:

	1.	In recent years the von Kármán constant has been subject to periodic scrutiny. Récemment, la constante de von Kármán a été réévaluée.
	2.	It is a ratio between the sediment fall velocity w s {\displaystyle w_{s}} and the upwards velocity on the grain as a product of the von Kármán constant κ {\displaystyle \kappa } and the shear velocity u ∗ {\displaystyle u_{*}} . Il est défini comme le rapport entre la vitesse de chute du sédiment (notée w s
	3.	In fluid dynamics, the von Kármán constant (or Kármán's constant), named for Theodore von Kármán, is a dimensionless constant involved in the logarithmic law describing the distribution of the longitudinal velocity in the wall-normal direction of a turbulent fluid flow near a boundary with a no-slip condition. En mécanique des fluides, la constante de von Kármán, nommée d'après Theodore von Kármán, est une constante sans dimension décrivant le profil logarithmique des vitesses d'un fluide turbulent sans glissement à la limite.
	4.	It was derived as, L = − u ∗ 3 κ g T Q ρ c p {\displaystyle L=-{\dfrac {u_{*}^{3}}{\kappa {\dfrac {g}{T}}{\dfrac {Q}{\rho c_{p}}}}}} where κ ≈ 0.40 {\displaystyle \kappa \approx 0.40} is the von Kármán constant, u ∗ {\displaystyle u_{*}} friction velocity, Q {\displaystyle Q} turbulent heat flux, and c p {\displaystyle c_{p}} heat capacity. Il a été démontré que : L = − u ∗ 3 κ g T Q ρ c p
