Helical Locomotion in Yield Stress Fluids
Farshad Nazari Kourosh Shoele, Hadi Mohammadigoushki
We report three stages for locomotion of a helical swimmer in yield stress fluids. In the first stage, the swimmer must overcome material's yield strain to generate rotational moti…

Axisymmetric Squirmers in Stokes Fluid with Nonuniform Viscosity
Patrick S. Eastham, Kourosh Shoele
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-swi…
