使用由混合边界条件产生的成对的对偶积分方程，提出了由于边界壁上的圆孔而导致剪切流与其他静止流体的相互作用的精确解。 Yan、Acrivos 和 Weinbaum 使用了这种流与通过孔的吸力驱动流 [J.体液。机甲。 （正在印刷中）] 渐进模拟流体撇渣和颗粒夹带进入小圆形侧孔。笛卡尔速度分量和动态压力可以非常简单地用环形坐标表示。
An exact solution, using pairs of dual integral equations that arise from mixed boundary conditions, is presented for the interaction, due to a circular hole in the bounding wall, of a shear flow with otherwise stationary fluid. Together with a suction‐driven flow through the hole, this flow has been used by Yan, Acrivos, and Weinbaum [J. Fluid. Mech. (in press)] to asymptotically model fluid skimming and particle entrainment into a small circular side pore. The Cartesian velocity components and dynamic pressure can be quite simply expressed in terms of toroidal coordinates.
