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 [...]

Modeling of Acoustic-Structural Coupling in a MEMS Hydrophone

Johnson H.T., Prevot L., Boston University, US

The coupling of acoustics and structural dynamics is of primary importance in the design of MEMS based microphones for use in liquid environments. A three-dimensional finite element study of acoustic-structural coupling is presented here for [...]

Modelling of Processes of Photoacoustic Diagnostic with Piezoelectric Detection

Vertsanova O., Perlov I., Tsyganok B., National Technical University of Ukraine, UA

Authors developed the one-dimensional mathematical model of piezoelectric detection of photoacoustic effect in thermally thick and optically opaque sample with subsurface defect. The model is developed in view of the assumptions of ideally rigid connection [...]
