abstract = {A mesoscopic hydrodynamic model to simulate synthetic
self-propelled Janus particles which is thermophoretically
or diffusiophoretically driven is here developed. We first
propose a model for a passive colloidal sphere which
reproduces the correct rotational dynamics together with
strong phoretic effect. This colloid solution model employs
a multiparticle collision dynamics description of the
solvent, and combines stick boundary conditions with
colloid–solvent potential interactions. Asymmetric and
specific colloidal surface is introduced to produce the
properties of self-phoretic Janus particles. A comparative
study of Janus and microdimer phoretic swimmers is performed
in terms of their swimming velocities and induced flow
behavior. Self-phoretic microdimers display long range
hydrodynamic interactions with a decay of 1/r2, which is
similar to the decay of gradient fields generated by
self-phoretic particle, and can be characterized as pullers
or pushers. In contrast, Janus particles are characterized
by short range hydrodynamic interactions with a decay of
1/r3 and behave as neutral swimmers.},
