Title (EN) METHOD FOR INCREASING THE ABILITY OF AT LEAST ONE DROPLET TO SLIDE OVER A MEDIUM
(FR) PROCEDE POUR FAVORISER LE GLISSEMENT D'AU MOINS UNE GOUTTE SUR UN SUPPORT
Abstract:
(EN) Method for increasing the ability of at least one droplet (15) to slide over a medium (5), method wherein an ultrasonic surface wave is generated in the medium with a sufficient amplitude to cause the droplet to deform in an inertio-capillary eigen-vibration mode, thus decreasing the attachment of the droplet to the medium, so as to make it easier for the droplet to move under the effect of an external force, the amplitude of the ultrasonic surface wave being insufficient to cause the droplet to deform asymmetrically to the point that it moves in the absence of the external force in the direction of propagation of the ultrasonic surface wave.
(FR) Procédé pour favoriser le glissement d'au moins une goutte (15) sur un support (5), procédé dans lequel une onde de surface ultrasonore est générée dans le support avec une amplitude suffisante pour amener la goutte à se déformer selon un mode inertio-capillaire de vibration propre réduisant ainsi l'accrochage de la goutte au support, de façon à faciliter le déplacement de la goutte sous l'effet d'une force externe, l'amplitude de l'onde de surface ultrasonore étant insuffisante pour entraîner une déformation asymétrique de la goutte au point de l'amener à se déplacer en l'absence de la force externe dans le sens de propagation de l'onde de surface ultrasonore.
