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…
Time-resolved velocity and pressure field quantification in a flow-focusing device for ultrafast microbubble production
Sarah Cleve, Christian Diddens, Tim Segers +2
Flow-focusing devices have gained great interest in the past decade, due to their capability to produce monodisperse microbubbles for diagnostic and therapeutic medical ultrasound…
Higher-order meniscus oscillations driven by flow-focusing leading to bubble pinch off and entrainment in a piezo acoustic inkjet nozzle
Arjan Frates, Maaike Rump, Roger Jeurissen +8
The stability of high-end piezo-acoustic drop-on-demand (DOD) inkjet printing is sometimes compromised by the entrainment of an air bubble inside the ink channel. Here, bubble pinc…
High-frequency acoustic droplet vaporization is initiated by resonance
Guilllaume Lajoinie, Tim Segers, Michel Versluis
Vaporization of low-boiling point droplets has numerous applications in combustion, process engineering and in recent years, in clinical medicine. However, the physical mechanisms…
Rayleigh-Taylor instability by segregation in an evaporating multi-component microdroplet
Yaxing Li, Christian Diddens, Tim Segers +3
The evaporation of multi-component droplets is relevant to various applications but challenging to study due to the complex physicochemical dynamics. Recently, Li (2018) reported e…
Wetting of two-component drops: Marangoni contraction versus autophobing
Michiel A. Hack, Wojciech Kwieciński, Olinka Ramírez-Soto +4
The wetting properties of multi-component liquids are crucial to numerous industrial applications. The mechanisms that determine the contact angles for such liquids remain poorly u…
