  Lattice Boltzmann Method(LBM) has achieved considerable success on simulating
complex flows. However, how to impose correct boundary conditions on the
fluid-solid interface with complex geometries is still an open question. Here
we proposed a velocity interpolation based bounce-back scheme where the ideas
of interpolated bounce-back and non-equilibrium extrapolation are combined. The
proposed scheme is validated by several well-defined benchmark cases. It is
shown that the proposed scheme offers a better accuracy at high Reynolds number
and less dependency on solids positions which may crucial in many engineering
and science applications.
