Fluid dynamics plays a crucial role in many cellular processes, including the locomotion of
cells such as bacteria and spermatozoa. These organisms possess flagella, slender …

Swimming micro-organisms often have to propel themselves in complex non-Newtonian
fluids. We carry out experiments with self-propelling helical swimmers driven by an …

Microorganisms are commonly found swimming in complex biological fluids such as mucus
and these fluids respond elastically to deformation. These viscoelastic fluids have been …

Viscoelastic fluids impact the locomotion of swimming microorganisms and can be
harnessed to devise new types of self-propelling devices. Here we report on experiments …

The fractional conformable derivative and its properties have been introduced recently.
Using this derivative we obtain a new class of smooth solutions for the Newton's law of …

We experimentally and theoretically study the dynamics of a low-Reynolds number helical
swimmer moving across viscosity gradients. Experimentally, a double-layer viscosity is …

An efficient, accurate, and flexible numerical method is proposed for the solution of the
swimming problem of one or more autophoretic particles in the purely diffusive limit. The …

The role of passive body dynamics on the kinematics of swimming micro-organisms in
complex fluids is investigated. Asymptotic analysis of small-amplitude motions of a finite …

The consideration of viscoelasticity within fluid dynamical boundary element methods has
traditionally required meshing over the whole flow domain. In turn, a major advantage of the …

Since their development in 2001, regularized stokeslets have become a popular numerical
tool for low-Reynolds-number flows since the replacement of a point force by a smoothed …
