Abstract Existing hybrid Level Set / Front Tracking methods have been developed for structured meshes and successfully used for efficient and accurate simulations of complex multiphase flows. This contribution extends the capability of hybrid Level Set / Front Tracking methods towards handling surface tension driven multiphase flows using unstructured meshes. Unstructured meshes are traditionally used in Computational Fluid Dynamics to handle geometrically complex problems. In order to simulate surface-tension driven multiphase flows on unstructured meshes, the LENT hybrid Level Set / Front Tracking method has been further developed. A new SAAMPLE Segregated Accuracy-driven Algorithm for Multiphase Pressure-Linked Equations is proposed, that increases the robustness of the unstructured Level Set / Front Tracking (LENT) method when simulating surface tension-driven flows. The LENT method is implemented in the OpenFOAM open source code for computational fluid dynamics.

示例：多相压力关联方程的分离精度驱动算法

摘要 现有的混合水平集/前沿跟踪方法已被开发用于结构化网格，并成功用于复杂多相流的高效和准确模拟。这一贡献扩展了混合水平集/前端跟踪方法的能力，以使用非结构化网格处理表面张力驱动的多相流。非结构化网格传统上用于计算流体动力学中以处理几何复杂的问题。为了在非结构化网格上模拟表面张力驱动的多相流，进一步开发了 LENT 混合水平集/前跟踪方法。提出了一种用于多相压力关联方程的新的 SAAMPLE 分离精度驱动算法，在模拟表面张力驱动的流动时，这增加了非结构化水平集/前沿跟踪 (LENT) 方法的鲁棒性。LENT 方法在计算流体动力学的 OpenFOAM 开源代码中实现。
