AB The  simulation  of  incompressible  flows  at  very  low  Reynolds  numbers  (Stokes  regime)  with  the  standard  lattice     Boltzmann method (collision-propagation algorithm) is hindered by a limitation of accuracy due to the relationship     between  viscosity  and  the  Mach  and  Reynolds  numbers.  We  present  a  multirelaxation-time  lattice-Boltzmann     method  with  modified  equilibrium  moments  that  allows  improvement  of  accuracy  for  a  given  resolution  at  very     low-Reynolds-number flows. This is paramount for liquid microflow simulations and for multiscale coupling in many     practical instances, such as when the fluid motion is highly influenced by bounding or particulate immersed solids. The     method as presented is restricted to steady-state flows, which include many fluid-flow applications at the microscale. The     viscous flow with slip of a liquid in a long microchannel, for which an analytical solution exists, has been used as the     test case.
