Title
(EN) INTERACTION CHAMBER WITH FLOW INLET OPTIMIZATION
(FR) CHAMBRE D'INTERACTION AYANT UNE OPTIMISATION D'ENTRÉE D'ÉCOULEMENT
Abstract
(EN)
A mixing assembly includes an inlet, an outlet and a mixing chamber, the inlet is fluidly connected to the outlet through a plurality of micro fluid flow paths in a direction perpendicular from the inlet. The micro fluid flow paths fluidly connect to the perpendicular inlet via a curved transition portion. The curved transition portion provides a more efficient flow path for the fluid to travel from the inlet to the micro fluid flow paths to the mixing chamber. By transitioning the direction change, flow resistance is decreased, and the fluid flow rate and shear rate is increased. Increased fluid flow rate and shear rate helps to increase consistency and quality of mixing, and to reduce particle size of the fluid in the mixing chamber.
(FR)
Un ensemble de mélange comprend une entrée, une sortie et une chambre de mélange, l'entrée est fluidiquement reliée à la sortie par une pluralité de micro-trajets d'écoulement de fluide dans une direction perpendiculaire à partir de l'entrée. Les micro-trajets d'écoulement de fluide sont reliés fluidiquement à l'entrée perpendiculaire par l'intermédiaire d'une partie de transition courbée. La partie de transition courbée fournit un trajet d'écoulement plus efficace pour que le fluide se déplace de l'entrée aux micro-trajets d'écoulement de fluide à la chambre de mélange. En effectuant une transition du changement de direction, la résistance d'écoulement est diminuée, et le débit de fluide et le taux de cisaillement sont augmentés. Un débit de fluide et un taux de cisaillement augmentés aident à augmenter une uniformité et une qualité de mélange, et à réduire une dimension de particule du fluide dans la chambre de mélange.
