Marangoni flow driven hysteresis and azimuthal symmetry breaking in evaporating binary droplets
Duarte Rocha, Detlef Lohse, Christian Diddens
The non-uniform evaporation rate at the liquid-gas interface of binary droplets induces solutal Marangoni flows. In glycerol-water mixtures (positive Marangoni number, where the mo…
Evaporating sessile droplets: solutal Marangoni effects overwhelm thermal Marangoni flow
Duarte Rocha, Philip L. Lederer, Pim J. Dekker +3
When an evaporating water droplet is deposited on a thermally conductive substrate, the minimum temperature will be at the apex due to evaporative cooling. Consequently, density an…
Symmetry Breaking in Chemical Systems: Engineering Complexity through Self-Organization and Marangoni Flows
Sangram Gore, Binaya Paudyal, Duarte Rocha +7
Far from equilibrium, chemical and biological systems can form complex patterns and waves through reaction-diffusion coupling. Fluid motion often interferes with these self-organiz…
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…
Deforming ice with drops
Duco van Buuren, Pallav Kant, Jochem G. Meijer +2
A uniform solidification front undergoes non-trivial deformations when encountering an insoluble dispersed particle in a melt. For solid particles, the overall deformation characte…
Evaporation of acoustically levitated bicomponent droplets: mass and heat transfer characteristics
Yuki Wakata, Xing Chao, Chao Sun +1
Evaporation of multicomponent droplets is important in a wide range of applications, albeit complex, and requires a careful investigation. We experimentally and numerically investi…
Non-monotonic surface tension leads to spontaneous symmetry breaking in a binary evaporating drop
Christian Diddens, Pim J. Dekker, Detlef Lohse
The evaporation of water/1,2-hexanediol binary drops shows remarkable segregation dynamics, with hexanediol-rich spots forming at the rim, thus breaking axisymmetry. While the segr…
Enhanced bubble growth near an advancing solidification front
Jochem G. Meijer, Duarte Rocha, Annemarie M. Linnenbank +2
Frozen water might appear opaque since gas bubbles can get trapped in the ice during the freezing process. They nucleate and then grow near the advancing solidification front, due…
