SedFoam 1.0: A multi-dimensional numerical model for sediment transport based on the two-phase flow formulation is developed. With closures of particle stresses and fluid-particle interaction, the model is able to resolve processes in the concentrated region of sediment transport and hence does not require conventional bedload/suspended load assumptions. The numerical model is developed in three spatial dimensions. However, in the existing versions, the model is only validated for Reynolds-averaged two-dimensional vertical (2DV) formulation. This numerical model is developed via the open-source CFD toolbox, OpenFOAM and the new solver is called SedFoam. We gratefully acknowledge developers involved in OpenFOAM, which is the foundation of SedFoam.

SedFoam 1.0：本研究开发了一款基于两相流理论框架的多维泥沙输运数值模型。通过引入颗粒应力与流固相互作用的封闭方案，该模型能够解析泥沙输运集中区域的流动过程，因此无需采用传统的推移质/悬移质假设。该数值模型的理论框架支持三维空间维度，但在现有版本中，仅针对雷诺平均二维垂向（2DV）公式完成了验证。本数值模型基于开源计算流体力学（Computational Fluid Dynamics, CFD）工具包OpenFOAM开发，新增的求解器命名为SedFoam。谨此感谢作为SedFoam开发基础的OpenFOAM全体开发者。
