Method and device for the controlled break-up of liquid jets

摘要

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 (4) having stationary motion to a plurality of mutually independent sectors and defined in a perforated surface (8);forming a head of liquid (10) in said sectors (7) near said perforated surface (8);causing said liquid to flow across said perforated surface (8) to form a plurality of second liquid jets (6);periodically changing with a predetermined frequency the momentum of the liquid fed to a predetermined sector (7) 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 said perforated surface (8) which is transmitted to the second liquid jets (6) causing their controlled break-up in a plurality of substantially monodispersed drops.
