dc.description.abstract
Hydrodynamically interacting microswimmers may collectively propel in a medium. In this work, we study pair swimming of chiral squirmers in the low Reynolds number region, considering both the near and far field interactions. The chiral squirmer [1,2] is a model spherical, non-deformable body with a chiral surface slip velocity. While the chiral squirmers are very close to each other, the lubrication effects become dominant. Due to lubrication force, either the squirmers repel each other monotonically or perform bounded motion until they separate from each other in the long time limit. Note that, in bounded motion, the separation distance between the chiral squirmers varies periodically. Hence, we observe three types of motion: 1. Monotonic divergence (the chiral squirmers monotonically repel each other from the beginning). 2. Divergence (the chiral squirmers attract each other initially before repelling each other in the long time limit). 3. Bounded motion. This study helps understand the collective motion of ciliated microorganisms.
