Phoretic flow in a three-dimensional wedge geometry
Abdallah Daddi-Moussa-Ider, Semyon Yakubovich, Maciej Lisicki
Understanding how chemically induced surface transport generates fluid motion in confined geometries is essential for the rational design of microscale pumping devices and active m…
Surfactant reorientation under shear: dynamic surface tension and droplet deformation
Alexandra J. Hardy, Abdallah Daddi-Moussa-Ider, Elsen Tjhung
Surfactants are amphiphilic molecules that are generally anisotropic rather than spherical. Their orientation is therefore governed by the interplay between shear-induced reorienta…
Analytical response functions for a compressible thin fluid layer with odd viscosity
Abdallah Daddi-Moussa-Ider, Yuto Hosaka, Shigeyuki Komura
Fluids composed of chiral active components can exhibit odd viscosity, a property that breaks time-reversal and parity symmetries. We investigate the hydrodynamic response to monop…
Self-diffusiophoretic propulsion in wedge confinement: The role of phoretic interactions
Abdallah Daddi-Moussa-Ider, Ramin Golestanian
We investigate the self-diffusiophoretic motion of a catalytically active spherical particle confined within a wedge-shaped domain. Using the Fourier-Kontorovich-Lebedev transform,…
Hydrodynamic flows induced by localized torques (rotlets) in wedge-shaped geometries
Abdallah Daddi-Moussa-Ider, Jakob Mihatsch, Michael J. Mitchell +2
Wedge-shaped geometries in low-Reynolds-number flows are of increasing importance, for instance, in the design of microfluidic devices. The corresponding Green's functions describi…
Kinetic theory of coupled binary-fluid-surfactant systems
Alexandra J. Hardy, Samuel Cameron, Steven McDonald +2
We derive a self-consistent hydrodynamic theory of coupled binary-fluid-surfactant systems from the underlying microscopic physics using Rayleigh's variational principle. At the mi…
