A rotor to establish a swirling flow in liquid(s) contained in a vessel. In one form the rotor includes two parallel spaced apart discs. An array of vanes is interposed between the discs. One of the discs is annular to define an inlet to the array of vanes. The inlet controls the size of an inner core region of the swirling flow. In another form the rotor has at least two hollow spokes directed radially outwardly from the central hub. The spokes each have a passage with an inlet directed toward the hub and a radially directed outlet. Rotation of the rotor produces a flow through the spokes that contributes to the rotational radially outward flow that establishes the swirling flow. In another form of the invention the rotor includes at least two blades directed radially outwardly from a central hub. The blades include at least one surface inclined to the direction of rotation of the rotor. The blades induce a flow in the axial direction as the rotationally outward flow is created to establish the swirling flow.
L'invention concerne un rotor permettant de produire un écoulement en vortex dans un ou des liquides contenus dans un récipient. Dans une forme de réalisation, le rotor comprend deux disques espacés parallèles. Un groupement de palettes est placé entre les disques. L'un des disques est annulaire afin de définir une entrée vers le groupement de palettes. L'entrée permet de régler la taille d'une zone de tourbillon interne de l'écoulement en vortex. Dans une autre forme de réalisation, le rotor comporte au moins deux bras creux dirigés radialement vers l'extérieur, à partir du moyeu central. Les bras présentent chacun un passage, avec une entrée dirigée vers le moyeu et une sortie dirigée radialement. La rotation du rotor produit un écoulement à travers les bras, qui facilite l'écoulement tourbillonnaire radial vers l'extérieur formant l'écoulement en vortex.
