摘要翻译：
研究了压力驱动Stokes流动在填充分数为0.1<=phi<=0.64时通过随机排列的球体的壁面剪切速率分布P(γ)。对于致密填料，P(gamma)是单调的近似指数的。当phi->0.1时，P(gamma)产生了与孤立球体绕流相对应的附加结构，可以得到精确的结果。基于力平衡理论，给出了平均壁面剪切速率的一个简单表达式。

英文摘要：
  The wall shear rate distribution P(gamma) is investigated for pressure-driven Stokes flow through random arrangements of spheres at packing fractions 0.1 <= phi <= 0.64. For dense packings, P(gamma) is monotonic and approximately exponential. As phi --> 0.1, P(gamma) picks up additional structure which corresponds to the flow around isolated spheres, for which an exact result can be obtained. A simple expression for the mean wall shear rate is presented, based on a force-balance argument.
