In this paper, a Lax-Wendroff type solver is developed to solve the governing equations for two-phase flows. By incorporating the source term into the numerical flux and approximating the cell volume force by the interfacial forces, the proposed scheme is able to restrain parasitic currents in two-phase systems. Numerical results suggest that the magnitude of the parasitic currents is considerably reduced, and the stability is also improved. Particularly, for a one-dimensional flat interface and a two-dimensional (2D) stationary droplet, the velocity fields drop to machine zero even with a large density ratio (1:1000). It is also found that the viscosity plays an important role in the suppression of parasitic currents when the density ratio is large.
