Active colloids are self-propelled particles moving in viscous fluids by consuming fuel from
their surroundings. Here, we review the numerical and theoretical modeling of active …

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 hydrodynamics of an archetypal low-Reynolds number swimmer, called “squirmer,”
near a wall has been numerically studied. For a single squirmer, depending on the …

The self-propulsion of a spherical squirmer–a model swimming organism that achieves
locomotion via steady tangential movement of its surface–is quantified across the transition …

Electrophoresis is the motion of a charged colloidal particle in an electrolyte under an
applied electric field. The electrophoretic velocity of a spherical particle depends on the …

We numerically investigate the hydrodynamics of a spherical swimmer carrying a rigid cargo
in a Newtonian fluid. This swimmer model, a 'squirmer', which is self-propelled by generating …

We simulated the motions and interactions of circular squirmers under gravity in a two-
dimensional channel at finite fluid inertia, aiming to provide a comprehensive analysis of the …

We investigate the hydrodynamics of a spherical and dumbbell-shaped swimmer in a
viscoelastic fluid, modelled by the Giesekus constitutive equation. The 'squirmer', a model of …

We simulated the sedimentation of two self-propelled particles in a two-dimensional (2D)
vertical channel using the lattice Boltzmann method. A 2D squirmer model was employed to …

The hydrodynamic behavior of a squirmer swimming in the flow of power-law fluid is studied
numerically with an immersed boundary-lattice Boltzmann method. The power-law fluids …
