The flow of a Newtonian liquid on rotating inclined surfaces with application to atomization
Spinning cup atomizers are used industrially to produce an
airborne spray. Often the size distribution of the spray is important.
The size distribution of the spray depends on the physical dimensions of
the cup, the operating-conditions and the physical properties of the
fluid to be atomized.
A spinning cup atomizer can be considered in the following way.
The liquid to be atomized is fed centrally on to the surface of the cup
where it begins to thin into a liquid film under the centrifugal action
of the rotating cup. As the liquid flows film-wise to the lip of the
cup, where atomization occurs, it obtains energy from the cup.
Obviously, efficient atomization will occur if the liquid reaches the
lip of the cup after it has picked up sufficient energy and if it was
evenly distributed on the cup initially. [Continues.
