摘要：这项研究中提出了适用于分析悬移质泥沙的三维耦合水沙交互作用模型。为了验证该模型，将其应用于稳定均匀流动和破浪带区域悬移质泥沙的水动力学实验研究。时均悬沙浓度实验数据证实了该模型在这两种流态下的预测能力。破浪带的数值结果显示，复杂的悬浮泥沙输移与3D涡旋运动有关，而3D涡旋运动是由破碎波形成的，研究结果表明，模型对于波浪条件的下悬浮泥沙输移研究的实用性。

Abstract：A 3D coupled fluid-sediment interaction model applicable to suspended sediment analysis is developed in this study. For validation, the developed model is applied to hydraulic experiments on suspended sediment in a steady uniform flow and a swash zone. For both flow conditions, the predictive capability of the model is demonstrated against experimental data in terms of time-averaged suspended sediment concentration. Numerical results for the swash zone show that complex suspended sediment transport relates to 3D vortex motion due to plunging breaking waves, and the results demonstrate the usefulness of the developed model in investigating suspended sediment transport under breaking waves.
