Abstract
A method for the controlled break-up of liquid jets for production of substantially monodispersed drops stands out for the fact that it comprises the steps of feeding a plurality of first liquid jets having steady motion to a plurality of mutually independent sectors and defined in a perforated surface, forming a head of liquid in the sectors near the perforated surface, causing the liquid to flow across the perforated surface to form a plurality of second liquid jets, periodically changing with a predetermined frequency the momentum of the liquid fed to a predetermined sector so as to impart to the liquid present in said sector a disturbance of predetermined magnitude consisting of a periodic change in the pressure near the perforated surface which is transmitted to the second liquid jets causing their controlled break-up in a plurality of substantially monodispersed drops.
