vFoam

The volume of fluid (VOF) method is a popular approach for multiphase flow modeling. The open-source computational fluid dynamics (CFD) software, OpenFOAM, has implemented a variety of VOF-based solvers and provides users a wide range of turbulence models. Since flows under the VOF framework belong to the variable-density incompressible flow category, the isothermal VOF-based solvers in OpenFOAM fail to use the correct turbulence models. vFoam is designed to solve this issue and with the hope to replace all the corresponding existing solvers in the future. With the object-oriented paradigm, vFoam guarantees the usability, reusability and maintainability of the codes. Aside from turbulence modeling, all other features in the original solvers are preserved in vFoam.流体体积法（Volume of Fluid, VOF）是多相流模拟领域的主流方法之一。开源计算流体动力学（Computational Fluid Dynamics, CFD）软件OpenFOAM已集成多款基于VOF的求解器，并为用户提供了丰富的湍流模型选型。由于VOF框架下的流动属于变密度不可压缩流范畴，OpenFOAM中原有的等温VOF类求解器无法适配正确的湍流模型。vFoam正是为解决这一问题而开发，并计划在未来替代所有现有同类求解器。vFoam采用面向对象编程范式，保障了代码的可用性、可复用性与可维护性。除湍流建模模块外，原始求解器的其余所有功能均在vFoam中得到完整保留。
