Abstract
The present invention relates to a device for ejecting an at least diphasic mixture, comprising an injection inlet (IN1, IN2) for a liquid (11) and a gas (G1), a distribution chamber (EMD) for producing a first liquid-gas mixture (MLG1), an ejection nozzle (EJ) of the first liquid-gas mixture in a main direction defined by a an axis-vector. The ejection nozzle has a geometry comprising, on its length at least, a minimal section or neck at a location (X) of the axis-vector. Amongst others things, due to the nozzle geometry, the expansion obtained inside the ejection nozzle allows the first liquid-gas mixture from the distribution chamber to be converted into a second mixture, according to the flow configuration, consisting for instance of a diphasic mist jet having an ejection range and liquid particle size that can be controlled according to the liquid and gas mass flow and to the absolute pressure at the injection inlet.
