本文应用Ladd等引入的晶格玻尔兹曼方法和粒子悬浮液的推广，研究了靠近剪切固体壁面的流体中悬浮粒子的输运现象和结构效应。我们发现在壁面附近出现了一个粒子自由区域，其宽度取决于剪切速率和粒子浓度。在低浓度下，壁面会形成平行的颗粒层，每层的颗粒数随着离壁面距离的增加而减少。
In this paper we apply the lattice Boltzmann method and an extension to particle suspensions as introduced by Ladd et al to study transport phenomena and structuring effects of particles suspended in a fluid near sheared solid walls. We find that a particle free region arises near walls, which has a width depending on the shear rate and the particle concentration. The wall causes the formation of parallel particle layers at low concentrations, where the number of particles per layer decreases with increasing distance from the wall.
