用奇异性方法求解Stokes方程，研究了沿流动方向排列的方形杆阵的剪切流动。对于占据库埃特通道一部分的各种阵列，确定了从0.001到0.1%的固体体积分数的流场。通过阵列边缘的滑移速度来量化阵列中的流动穿透。这一速度比流动穿过阵列时要大得多，但仍然低于使用布林克曼方程预测的值。
Shear flow over a square array of widely-spaced rods aligned with the flow is investigated using singularity methods to solve Stokes equation. The flow field is determined for various arrays occupying a fraction of a Couette channel, for solid volume fractions from 0.001 to 0.1. Flow penetration into an array is quantified by the slip velocity at the array edge. This velocity is much greater than when the flow is across the array but still less than the value predicted by the use of Brinkman's equation.
