abstract = {The dynamics and motion of multi-ciliated microswimmers
with a spherical body and a small number N (with 5<N<60) of
cilia with length comparable to the body radius, is
investigated by mesoscale hydrodynamics simulations. A
metachronal wave is imposed for the cilia beat, for which
the wave vector has both a longitudinal and a latitudinal
component. The dynamics and motion is characterized by the
swimming velocity, its variation over the beat cycle, the
spinning velocity around the main body axis, as well as the
parameters of the helical trajectory. Our simulation results
show that the microswimmer motion strongly depends on the
latitudinal wave number and the longitudinal phase lag. The
microswimmers are found to swim smoothly and usually spin
around their own axis. Chirality of the metachronal beat
pattern generically generates helical trajectories. In most
cases, the helices are thin and stretched, i.e., the helix
radius is about an order of magnitude smaller than the
pitch. The rotational diffusion of the microswimmer is
significantly smaller than the passive rotational diffusion
of the body alone, which indicates that the extended cilia
contribute strongly to the hydrodynamic radius. The swimming
velocity is found to increase with the cilia number N with a
slightly sublinear power law, consistent with the behavior
expected from the dependence of the transport velocity of
planar cilia arrays on the cilia separation.},
