Unsteady drag force on an immersed sphere oscillating near a wall
Zaicheng Zhang, Vincent Bertin, Martin Essink +6
The unsteady hydrodynamic drag exerted on an oscillating sphere near a planar wall is addressed experimentally, theoretically, and numerically. The experiments are performed by usi…
Exact solutions for viscous Marangoni spreading
T. Bickel, F. Detcheverry
When surface-active molecules are released at a liquid interface, their spreading dynamics is controlled by Marangoni flows. Though such Marangoni spreading was investigated in dif…
Stokes equation in a semi-infinite region: generalization of Lamb solution and applications to Marangoni flows
G. Koleski, T. Bickel
We consider the creeping flow of a Newtonian fluid in a hemispherical region. In a domain with spherical, or nearly spherical, geometry, the solution of Stokes equation can be expr…
Surfactant-driven instability of a divergent flow
G. Koleski, J. -C. Loudet, A. Vilquin +2
Extremely small amounts of surface-active contaminants are known to drastically modify the hydrodynamic response of the water-air interface. Surfactant concentrations as low as a f…
Modification of the fluctuation dynamics of ultra-thin wetting films
C. Clavaud, M. Maza-Cuello, C. Frétigny +2
We report on the effect of intermolecular forces on the fluctuations of supported liquid films. Using an optically-induced thermal gradient, we form nanometer-thin films of wetting…
Azimuthal instability of the radial thermocapillary flow around a hot bead trapped at the water-air interface
G. Koleski, A. Vilquin, J. -C. Loudet +2
We investigate the radial thermocapillary flow driven by a laser-heated microbead in partial wetting at the water-air interface. Particular attention is paid to the evolution of th…
