Wall-curvature driven dynamics of a microswimmer

Abstract
We study the dynamics of a microswimmer near a wall with arbitrary curvature using theory and lattice Boltzmann simulations. The results are presented using several measures with experimental relevance. Extending the previous works on swimmer dynamics near a flat wall, we comprehensively explore the swimmer dynamics near flat, concave, and convex walls. We find that swimmers exhibit a greater affinity towards a concave boundary compared to a convex boundary. In addition, the combined effect of convex and concave walls is studied by confining the swimmer in an annulus.
