Free Surface Flow and Acousto-Elastic Interaction in Piezo Inkjet
Océ Technologies B.V., NL
Keywords: inkjet, acoustics, drop formation, two-phase flow, fluid-structure interaction
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 surface flow with surface tension. Added to our measurements this reveals the phenomena involved in our main goal: firing droplets of ink at a very high rate with any desired shape, velocity, dimension and a reliability as high as possible.
