Drop formation mechanisms in piezo-acoustic inkjet

Wijshoff H.M.A., Océ Technologies B.V., NL

Drops are generated with a piezo inkjet device. A piezo actuator drives each channel. Drops are measured with stroboscopic illumination or high-speed camera recordings. The phenomena inside the channels are hard to measure. Modeling give [...]

Free Surface Flow and Acousto-Elastic Interaction in Piezo Inkjet

Wijshoff H., Océ Technologies B.V., NL

Modeling plays an essential role in our research on new inkjet technologies. Structural modeling with Ansys includes piezo-electricity. Acoustic modeling in Ansys and Matlab involves fluid-structure interaction. CFD modeling with Flow3D includes wall-flexibility and free [...]
