      恩,我这边用的是MFIX,还没有植入。openfoam也有人植入过的,【A general numerical model for surface waves generated by granular material

    • RE: 拉格朗日中的湍流分散力模型

      湍流分散力在泥沙的悬浮运动中非常重要。欧拉方程中湍流分散力有两种表示形式:1.如上文所言,在拖曳力里面加一分散项;2.在连续方程中考虑脉动速度,
      如文献【(2011). A general two-phase turbulent flow model applied to the study of sediment transport in open channels. International Journal of Multiphase Flow, 37(9), 1099-1108.】中方程2的写法。
      相关推导过程在文献【 Jha, S. K. , & Fabián A. Bombardelli. (2010). Toward two-phase flow modeling of nondilute sediment transport in open channels. Journal of Geophysical Research Earth Surface, 115(F3), -.】里面的附录里也有。
