Many clarifiers have devices to stir the bottom of the sludge blanket by mechanical means. The immediate consequence is the destruction of the floc already formed (destruction due to the thixotropic properties of the sludge), a reduction in the concentration of solid matter in the sludge blanket and the formation of eddies which tend to move towards the top of the clarifier. 3, record 2, English, - turbulence

La modélisation dynamique de la turbulence a des applications importantes dans la prévision météorologique ou la propulsion des navires et des avions. Suivant L.D. Landeau (1944) la turbulence naît du très grand nombre de perturbations indépendantes (degrés de liberté) se développant en différents points d'un fluide. Depuis les travaux de D. Ruelle et F. Takens en 1971, on a démontré expérimentalement et mathématiquement qu'il suffit de trois degrés de liberté pour provoquer la turbulence d'un système car la moindre erreur initiale a des conséquences croissantes imprévisibles sur l'évolution de celui-ci. 3, record 3, French, - turbulence
