Breakup of a laminar jet
WebSep 1, 2024 · Breakup behaviors of laminar liquid jets with continuous droplets formation were numerically studied. Results verified that satellite droplets formation would destroy … WebBasically, it works on the principle of laminar jet break up. A laminar flow liquid jet forms by extrusion of a polymer solution through a selected nozzle, and it breaks-up into small uniform droplets of equal size owing to the application of a superimposed vibrational frequency at a defined amplitude . To avoid droplets coalescence, an ...

WebOct 1, 1999 · However, in the case of a vertically injected laminar jet when the injection velocity was comparatively low, the liquid column diameter changed vertically by the gravity effect. It seemed that the surface wave structure and breakup phenomena were influenced by the change of liquid column diameter. WebRayleigh demonstrated that controlled break-up of laminar jets into uniform droplets of equal size can be achieved simply by applying a permanent sinusoidal force at defined …
