Principle of Laminar Jet Break-Up VARD2Go

The electromagnetic laminar jet break-up
technology is based on the principle that a
laminar jet of a liquid feed passing a nozzle
of appropriate diameter is broken into equally sized droplets by a superimposed mechanical vibration. The vibration has to be done in resonance of the Plateau-Rayleigh instability and leads to very uniform droplets.

The Plateau–Rayleigh instability is named
for Joseph Plateau and Lord Rayleigh who
in 1873 found experimentally that a vertically
falling stream of water will break up into
drops if its length (so called “wave length of
disturbance” in specialist literature) is greater than about 3.13 to 3.18 times its diameter.

Using the natural liquid instability and replacing the natural irregular disturbances with the regular permanent mechanical vibration,
small uniform droplets are produced.
The droplets are further processed
in order to form particles by crosslinking or
polymerization or other hardening process
of the liquid feed.
The particle diameter can be predicted and
controlled by choosing the nozzle diameter,
volumetric flow and superimposed frequency.
