QUE SIGNIFIE TURBULENCE EN ANGLAIS
Turbulence
Dans la dynamique des fluides, la turbulence ou le flux turbulent est un régime d'écoulement caractérisé par des changements de propriété chaotiques. Ceci inclut une faible diffusion de momentum, une forte convection et une variation rapide de la pression et de la vitesse dans l'espace et le temps. Le flux dans lequel l'énergie cinétique découle en raison de l'action de la viscosité moléculaire fluide est appelé flux laminaire. Bien qu'il n'y ait pas de théorème reliant le nombre non-dimensionnel de Reynolds à la turbulence, les flux à des nombres de Reynolds supérieurs à 5000 sont généralement turbulents, alors que ceux à faible nombre de Reynolds restent habituellement laminaires. Dans le flux de Poiseuille, par exemple, la turbulence peut d'abord être maintenue si le nombre de Reynolds est supérieur à une valeur critique d'environ 2040; De plus, la turbulence est généralement entrecoupée avec un flux laminaire jusqu'à un nombre plus grand de Reynolds d'environ 4000. En écoulement turbulent, des tourbillons instables apparaissent sur de nombreuses échelles et interagissent les uns avec les autres. En raison de la couche limite, la friction de la peau augmente. La structure et l'emplacement de la séparation des couches limites changent souvent, entraînant parfois une réduction de la traînée globale.
définition de turbulence dans le dictionnaire anglais
La première définition de la turbulence dans le dictionnaire est un état ou une condition de confusion, de mouvement ou d'agitation; désordre. Une autre définition de la turbulence est l'instabilité locale dans l'atmosphère, les océans ou les rivières. La turbulence est également un écoulement turbulent dans un liquide ou un gaz.
