Influence of surfactants on the electrohydrodynamic stretching of water drops in oil
In this paper we present experimental and numerical studies of the electrohydrodynamic stretching of a sub-millimetre-sized salt water drop, immersed in oil with added non-ionic surfactant, and subjected to a suddenly applied electric field of magnitude approaching 1 kV/mm. By varying the drop size,...
The transition in settling velocity of surfactant-covered droplets from the Stokes to the Hadamard–Rybczynski solution
The exact solution for a small falling drop is a classical result by Hadamard and Rybczynski. But experiments show that small drops fall slower than predicted, giving closer agreement with Stokes’ result for a falling hard sphere. Increasing the drop size, a transition between these two extremes is ...
A multiscale method for simulating fluid interfaces covered with large molecules such as asphaltenes
The interface between two liquids is fully described by the interfacial tension only for very pure liquids. In most cases the system also contains surfactant molecules which modify the interfacial tension according to their concentration at the interface. This has been widely studied over the years,...
