标题： Discontinuous Shear Thickening of a Moderately Dense Inertial Suspension of Hydrodynamically Interacting Frictionless Soft Particles

摘要： 我们演示了即使在由流体力学相互作用的无摩擦软颗粒组成的适度密集惯性悬浮液中，也会发生不连续剪切增稠（DST）现象，这借助润滑-摩擦离散单元法得以实现。 该模拟表明，如果悬浮液的惯性和颗粒的柔软度很重要，则可以在较低密度下观察到DST现象。 我们还确认，不考虑流体动力相互作用的情况下，DST的行为可以用 kinetic theory 近似表示。 显示英文摘要

摘要： We demonstrate that a discontinuous shear thickening (DST) can take place even in a moderately dense inertial suspension consisting of hydrodynamically interacting frictionless soft particles with the aid of the Lubrication-Friction Discrete Element Method. This simulation indicates that the DST can be observed for lower densities, if the inertia of suspensions and softness of particles are important. We also confirm that the behavior of DST is approximated by the kinetic theory without consideration of hydrodynamic interactions.
