摘要

Fractional propagation is used to reduce the spurious velocities for multiphase lattice Boltzmann models.The numerical results show that the maximum spurious velocity at the interfaces could be reduced effectively in comparison with some o1 the early models.Eight spurious eddies,which previously existed in the D2Q9 model at the interfaces of two-phase flows,are completely eliminated.Simulations are used to confirm these results using different parameters.
