Acoustically-Induced Inkjets
A combination of acoustically induced momentum and thermally induced surface tension variation can be used to separate a droplet from the ink stream. The images to the right show a simulated droplet created by thermal inducement and an experimentally observed droplet.
The animation shows an acoustically
induced jet, which is unable to break off due to high surface tension forces
and the same situation with heat added. The heated jet breaks off a droplet.
