Upstream motion of oil droplets in co-axial Ouzo flow due to Marangoni forces
Steffen Bisswanger, Duarte Rocha, Sebastian Dehe +4
To explore the physicochemical hydrodynamics of phase-separating ternary liquids (Ouzo-type), a binary oil-ethanol mixture is introduced into a co-flowing stream of water. Oil drop…
Internal flow and concentration in neighbouring evaporating binary droplets and rivulets
Pim J. Dekker, Duarte Rocha, Christian Diddens +1
In this paper, the evaporation of neighbouring multi-component droplets or rivulets - often found in applications such as inkjet printing, spray cooling, and pesticide delivery - i…
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…
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…
Bifurcation tracking on moving meshes and with consideration of azimuthal symmetry breaking instabilities
Christian Diddens, Duarte Rocha
We present a black-box method to numerically investigate the linear stability of arbitrary multi-physics problems. While the user just has to enter the system's residual in weak fo…
