英文摘要	Motivated by inconveniences of present hybrid methods, a gradient-augmented hybrid interface capturing method (GAHM) is presented for incompressible two-phase flow. A front tracking method (FTM) is used as the skeleton of the GAHM for low mass loss and resources. Smooth eulerian level set values are calculated from the FTM interface, and are used for a local interface reconstruction. The reconstruction avoids marker particle redistribution and enables an automatic treatment of interfacial topology change. The cubic Hermit interpolation is employed in all steps of the GAHM to capture subgrid structures within a single spacial cell. The performance of the GAHM is carefully evaluated in a benchmark test. Results show significant improvements of mass loss, clear subgrid structures, highly accurate derivatives (normals and curvatures) and low cost. The GAHM is further coupled with an incompressible multiphase flow solver, Super CE/SE, for more complex and practical applications. The updated solver is evaluated through comparison with an early droplet research.; supported by the National Natural Science Foundation of China,the Science and Technology Development Foundation of China Academy of Engineering Physics (CAEP), China,the Defense Industrial Technology Development Program of China; SCI(E); EI; 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); kliu@pku.edu.cn; 6; 064701-1-064701-7; 25
