Role of surfactants on droplet formation in piezoacoustic inkjet printing across microsecond-to-second timescales
Maaike Rump, Christian Diddens, Uddalok Sen +3
In piezo acoustic drop-on-demand inkjet printing a single droplet is produced for each piezo driving pulse. This droplet is typically multicomponent, including surfactants to contr…
Resonance behavior of a compliant piezo-driven inkjet channel with an entrained microbubble
Hans Reinten, Yogesh Jethani, Arjan Fraters +4
Microbubbles entrained in a piezo-driven drop-on-demand (DOD) printhead disturb the acoustics of the microfluidic ink channel and thereby the jetting behavior. Here, the resonance…
Buckling of lipidic ultrasound contrast agents under quasi-static load
Georges Chabouh, Benjamin van Elburg, Michel Versluis +3
Collapse of lipidic ultrasound contrast agents under high-frequency compressive load has been historically interpreted by the vanishing of surface tension. By contrast, buckling of…
Selective evaporation at the nozzle exit in piezoacoustic inkjet printing
Maaike Rump, Uddalok Sen, Roger Jeurissen +5
In practical applications of inkjet printing the nozzles in a printhead have intermittent idle periods, during which ink can evaporate from the nozzle exit. Inks are usually multic…
Vorticity-induced flow-focusing leads to bubble entrainment in an inkjet printhead: synchrotron X-ray and volume-of-fluid visualizations
Maaike Rump, Youssef Saade, Uddalok Sen +4
The oscillatory flows present in an inkjet printhead can lead to strong deformations of the air-liquid interface at the nozzle exit. Such deformations may lead to an inward directe…
The asymmetric coalescence of two droplets with different surface tensions is caused by capillary waves
Michiel A. Hack, Patrick Vondeling, Menno Cornelissen +4
When two droplets with different surface tensions collide, the shape evolution of the merging droplets is asymmetric. Using experimental and numerical techniques, we reveal that th…
