摘要：In this paper, we propose an improved tangent of hyperbola for interface capturing with slope weighting (THINC/SW) scheme for computing incompressible two-phase flows with surface tension on fixed Eulerian grids. The new scheme possesses the following major new properties in comparison with the original THINC/SW scheme: (i) providing a simple and accurate approach for generating a smooth level set (LS) field from the discontinuous volume-of-fluid field, (ii) determining the interface slope from the cogenerated LS field, and (iii) evaluating the surface tension force by the cogenerated LS field. We verified the proposed scheme with the widely used advection benchmark tests and multifluid simulations. Numerical results reveal that the new scheme can not only improve the solution quality of interface capturing but also increase the accuracy of curvature estimates and suppress the parasitic currents. © 2018 John Wiley & Sons, Ltd.
