Lift forces are widespread in hydrodynamics. These are typically observed for big and fast
objects and are often associated with a combination of fluid inertia (ie large Reynolds …

In the study of fluid dynamics and transport phenomena, key quantities of interest are often
the force and torque on objects and total rate of heat/mass transfer from them …

The Marangoni effect refers to fluid flow induced by a gradient in surface tension at a fluid-
fluid interface. We determine the full three-dimensional Marangoni flow generated by a non …

Active droplets swim as a result of the nonlinear advective coupling of the distribution of
chemical species they consume or release with the Marangoni flows created by their non …

We investigate the motion of a sedimenting drop in the presence of an electric field in an
arbitrary direction, otherwise uniform, in the limit of small interface deformation and low …

Rheotaxis is a well-known phenomenon among microbial organisms and artificial active
colloids, wherein the swimmers respond to an imposed flow. We report the first experimental …

We address the dynamics of a surfactant-laden droplet on a solid surface in simple shear
flow numerically. Our analysis uses the front-tracking method to take surfactant transport into …

The mechanism of surface-charge convection, quantified by the electric Reynolds number
respectively denote the ratios of resistivity, permittivity and viscosity values in the …

The effect of a uniform electric field on the motion of a drop in an unbounded plane
Poiseuille flow is studied analytically. The drop and suspending media are considered to be …

Active particles disturb the fluid around them as force dipoles, or stresslets, which govern
their collective dynamics. Unlike swimming speeds, the stresslets of active particles are …
