Abstract

Procédé de production d'un jet gazeux/liquide constitué de gouttelettes de liquide finement atomisées, se déroulant comme suit: un mélange gaz/liquide est admis dans un tube (5) muni d'au moins une buse présentant un orifice de sortie; un écoulement à effet bouchon (écoulement dont les parties gazeuses et les parties liquides sont séparées) se forme dans le tube (5) avant sa sortie de la buse (6); l'écoulement de sortie est soumis à un champ acoustique dont la fréquence est essentiellement un multiple de celle de l'écoulement à effet bouchon ou de préférence, voisine.
