提出了一种新的数值模拟方法，用于求解无界流体中细长颗粒的低雷诺数流动问题。该技术扩展了斯托克斯动力学的原理，多极矩展开法，椭球粒子形状。该方法适用于长椭球体，特别是，并显示出有效和准确的比较与其他数值方法的斯托克斯流。流体动力学相互作用的重要性说明了在一个简单的剪切流的沉降球体和颗粒的例子。
A new simulation method is presented for low-Reynolds-number flow problems involving elongated particles in an unbounded fluid. The technique extends the principles of Stokesian dynamics, a multipole moment expansion method, to ellipsoidal particle shapes. The methodology is applied to prolate spheroids in particular, and shown to be efficient and accurate by comparison with other numerical methods for Stokes flow. The importance of hydrodynamic interactions is illustrated by examples on sedimenting spheroids and particles in a simple shear flow.
