<p>The present invention pertains to the field of jet-generation techniques and more precisely relates to a liquid-gas jet apparatus which comprises an axially symmetrical active nozzle as well as a mixing chamber. When the ratio between the surface area at the smallest flow section of the mixing chamber and the surface area at the smallest flow section of the nozzle varies between 10 and 200, the value of the radial and angular misalignment between the active nozzle and the mixing chamber varies respectively between 0.10 and 12 mm and between 2'' and 5°30'. When the above-mentioned ratio varies between 200 and 1600, the radial and angular misalignment value may vary respectively between 0.14 and 25 mm and between 2.5'' and 10°30'. A jet apparatus realised according to the above-mentioned dimensions exhibits an improved operation efficiency.</p> |
