标题： An OpenFOAM face-centred solver for incompressible flows robust to mesh distortion

摘要： 本文综述了中心有限体积法（CCFV）中常见的网格诱导误差，并指出面对这些误差，重心有限体积法（FCFV）提供了一种有竞争力的解决方案。特别是，一个针对不可压缩层流的稳健FCFV求解器被集成到OpenFOAM中，并在一系列稳态和瞬态基准测试中进行了验证。该方法在最优收敛性、精度、稳定性和鲁棒性方面优于标准的simpleFoam和pimpleFoam算法。特别强调的是，本文通过数值演示证明了FCFV方法处理非正交、拉伸以及偏斜网格的能力，而CCFV方案在这些情况下表现出不足。 显示英文摘要

摘要： This work presents an overview of mesh-induced errors commonly experienced by cell-centred finite volumes (CCFV), for which the face-centred finite volume (FCFV) paradigm offers competitive solutions. In particular, a robust FCFV solver for incompressible laminar flows is integrated in OpenFOAM and tested on a set of steady-state and transient benchmarks. The method outperforms standard simpleFoam and pimpleFoam algorithms in terms of optimal convergence, accuracy, stability, and robustness. Special attention is devoted to motivate and numerically demonstrate the ability of the FCFV method to treat non-orthogonal, stretched, and skewed meshes, where CCFV schemes exhibit shortcomings.
