The ciliary locomotion and feeding of an axisymmetric micro-swimmer in a complex fluid whose viscosity depends on nutrient concentration are investigated numerically. The micro-swimmer is modeled as having spheroidal geometry, and ciliary beating is modeled by a slip velocity; i.e. a squirmer is adapted. Looking at the coupling between swimming and feeding of spheroidal squirmers, it is found that swimming speed and feeding are most affected by a non-uniform viscosity environment when the ratio… 
The effect of particle geometry on squirming through a shear-thinning fluid

Squirmers are models of a class of microswimmers, such as ciliated organisms and phoretic particles, that self-propel in fluids without significant deformation of their body shape. Available
Geometric phase methods with Stokes theorem for a general viscous swimmer
Abstract The geometric phase techniques for swimming in viscous flows express the net displacement of a swimmer as a path integral of a field in configuration space. This representation can be
Reorientation dynamics of microswimmers at fluid-fluid interfaces
We study the orientational and translational dynamics of spherical microswimmers trapped at fluid interfaces, in terms of the force dipole and source dipole components of their flow field. Using

Multiphase flow with self-driven particles is ubiquitous and complex. Exploring the flow properties has both important academic meaning and engineering value. This review emphasizes some recent
Hydrodynamics of active particles in viscosity gradients
The introduction of a particle into a preexisting nonuniform viscosity field will generally modify the viscosity field in order to satisfy boundary conditions on the particle surface. Here we discuss
Squirmers with swirl at low Weissenberg number
Abstract We investigate aspects of the spherical squirmer model employing both large-scale numerical simulations and asymptotic methods when the squirmer is placed in weakly elastic fluids. The

An axisymmetric squirmer in a Bingham viscoplastic fluid is studied numerically to determine the effect of a yield stress environment on locomotion. The nonlinearity of the governing equations
Fore-aft clearance controls how three-dimensional confinement affects micropropulsion
Systems of active particles are often affected by confinement due to nearby boundaries. Recently, there has been interest in the effect of confinement by complex three dimensional geometries, as

Stirring by squirmers
We analyse a simple ‘Stokesian squirmer’ model for the enhanced mixing due to swimming micro-organisms. The model is based on a calculation of Thiffeault & Childress (Phys. Lett. A, vol. 374, 2010,
Generalized squirming motion of a sphere
A number of swimming microorganisms, such as ciliates (Opalina) and multicellular colonies of flagellates (Volvox), are approximately spherical in shape and swim using beating arrays of cilia or
Locomotion of a microorganism in weakly viscoelastic liquids.
TLDR
Results show that "neutral" squirmers are unaffected by viscoelasticity, whereas "pullers" and "pushers" are slowed down and hastened, respectively, and the power dissipated by the swimming microorganism and the "swimming efficiency" are analytically quantified.

TLDR
This work considers the squirmer model as a general locomotion model to represent different types of swimmers and determines optimal shear rates at which the swimming efficiency can be substantially enhanced compared with the Newtonian case.
