摘要

A novel unstructured VoF scheme has been developed and coupled with a Lagrangian approach for describing secondary droplets and secondary breakup. The VoF-based scheme is geometric and un-split, and exactly conserves mass. A number of verification cases have been performed to assess the accuracy and performance of the method. Most importantly, the entire methodology is developed in the setting of unstructured grids, allowing the accurate body-fitted treatment of complex geometries. As a demonstration of the unstructured capability, liquid atomization in swirling crossflow was simulated for a high-shear swirling injector.
