abstract = {The swimming properties of an E. coli-type model bacterium
are investigated by mesoscale hydrodynamic simulations,
combining molecular dynamics simulations of the bacterium
with the multiparticle particle collision dynamics method
for the embedding fluid. The bacterium is composed of a
spherocylindrical body with attached helical flagella, built
up from discrete particles for an efficient coupling with
the fluid. We measure the hydrodynamic friction coefficients
of the bacterium and find quantitative agreement with
experimental results of swimming E. coli. The flow field of
the bacterium shows a force-dipole-like pattern in the
swimming plane and two vortices perpendicular to its
swimming direction arising from counterrotation of the cell
body and the flagella. By comparison with the flow field of
a force dipole and rotlet dipole, we extract the
force-dipole and rotlet-dipole strengths for the bacterium
and find that counterrotation of the cell body and the
flagella is essential for describing the near-field
hydrodynamics of the bacterium.},
