abstract = {In contrast to most real fluids, angular momentum is not a
locally conserved quantity in some mesoscopic simulation
methods. Here we quantify the importance of this
conservation in the flow fields associated with different
colloidal systems. The flow field is analytically calculated
with and without angular momentum conservation for the
multiparticle collision dynamics (MPC) method, and
simulations are performed to verify the predictions. The
flow field generated around a colloidal particle moving
under an external force with slip boundary conditions
depends on the conservation of angular momentum, and the
amplitude of the friction force is substantially affected.
Interestingly, no dependence on the angular momentum
conservation is found for the flow fields generated around
colloids under the influence of phoretic forces. Moreover,
circular Couette flow between a no-slip and a slip cylinder
is investigated, which allows us to validate one of the two
existing expressions for the MPC stress tensor.},
