标题： Comparison of bulk properties of wet granular materials using different capillary force approximations

摘要： 我们对分裂底剪切细胞中的湿颗粒物质进行了离散元方法模拟。 为了计算颗粒之间液体桥产生的毛细力，我们使用了三种不同的近似方法。 剪切细胞的模拟显示，整体内聚力随着液体表面张力的增加而线性增加，所有近似方法的结果一致。 然而，宏观摩擦系数仅与表面张力有微弱的相关性。 显示英文摘要

摘要： We perform Discrete Element Method simulations of wet granular matter in a split-bottom shear cell. To calculate the capillary forces from the liquid bridges between the grains, we used three different approximations. The simulations of the shear cell showed a linear increase in bulk cohesion with the surface tension of the liquid, consistently for all approximations. However, the macroscopic friction coefficient shows only a weak dependence on surface tension.
