Title (EN) METHODS AND APPARATUS FOR FLOW-CONTROLLED WETTING
(FR) PROCÉDÉS ET APPAREIL POUR LE MOUILLAGE EN FLUX RÉGULÉ
Abstract: front page image
(EN)Methods of determining a first position at which a dispersed phase droplet wets a surface of a channel are provided herein. The methods include immersing the dispersed phase droplet in a continuous phase fluid, wherein the continuous phase fluid is immiscible with the dispersed phase droplet, subsequently flowing the dispersed phase droplet in the continuous phase through the channel at a dispersed phase droplet velocity, wherein the dispersed phase droplet is separated from the surface by a film of the continuous phase fluid having a film thickness, and reducing the film thickness to rupture the film at the first position, wherein the droplet wets the surface at the first position.
(FR)La présente invention porte sur des procédés de détermination d'un premier endroit auquel une gouttelette de phase dispersée mouille une surface d'un canal. Les procédés comprennent l'immersion de la gouttelette de phase dispersée dans un fluide de phase continue, le fluide de phase continue n'étant pas miscible avec la gouttelette de phase dispersée, par la suite l'écoulement de la gouttelette de phase dispersée dans la phase continue dans le canal à une certaine vitesse de gouttelette de phase dispersée, la gouttelette de phase dispersée étant séparée de la surface par un film du fluide de phase continue ayant une certaine épaisseur de film, et la réduction de l'épaisseur de film pour casser le film au premier endroit, la gouttelette mouillant la surface au premier endroit.
