  • Device for generating a jet of two-phase fluid
    Patent number: 12582857
    Abstract: A device for generating a jet of two-phase fluid, comprising a nozzle having a main duct that is fed with a pressurized gaseous fluid and opens into a mixing chamber, and at least one secondary duct that is fed by at least one pressurized fluid and opens into the mixing chamber in a direction forming a non-zero angle with the axis of the main duct. The mixing chamber has a convergent-divergent cylindrical wall having a constriction defining an opening in the plane perpendicular to the axis of the main duct. The convergent part of the wall has a frustoconical region in the continuation of the axis of the at least one secondary duct so as to form a fragmentation chamber for the liquid phase.
