摘要
从两相流的基本方程出发建立了一个研究悬移质泥沙非平衡输移的数值模型。基本方程中考虑了相间相对运动的影响,水相和颗粒相通过相间作用力进行耦合,雷诺方程采用k-ε-Ap紊流模型封闭。对模型进行验证后将其应用于航道横断面的悬移质泥沙运动数值模拟。
A numerical model for non-equilibrium suspended sediment transport is established based on the basic equations of two-phase flow. The model considers the relative motion between different phases. The fluid phase and the particle phase are coupled by forces. Model k-ε-A is utilized to deal with the turbulence. The model is applied to simulate the motion of channel suspended sediment after its effectiveness is validated.
