摘要：<p>A method for production particles of a first fluid (f1) in a second fluid (f2), said fluids (f1 and f2) being non-miscible, wherein the first fluid (f1) is fed into a cavity (1) sealed by at least one membrane (3) comprising a predetermined number of holes (5i) and separating the first fluid (f1) from the second fluid (f2) outside the cavity (1), the membrane (3) is energised so that it vibrates at a frequency determined according to the mechanical resonance of the membrane (3), and particles (4i) of the first fluid (f1) are formed in the second fluid (f2) when said first fluid (f1) flows through the holes (5i) in the membrane (3), by means of the combined effect of the pressure exerted by the first fluid (f1) on the membrane (3) and the vibration of said membrane (3). The size of the holes is determined according to the amplitude of the combined effect of pressure and vibration, and the size of the holes (5i) in the membrane (3), the particles (4i) of the first fluid (f1) being released into the second fluid (f2) from the membrane (3) once their size is close to that of said holes (5i). The method is useful in the field of the environment, in particular for oxygenating water, as well as in the field of medicine, particularly in vascular tomography, etc.</p>
