流动惯性引起的径向漂移和布朗运动引起的扩散的共同作用显著地改变了管道束缚悬浮体的径向概率分布和轴向弥散。这种相互作用取决于佩莱特Pe和雷诺Re数的乘积，因此，即使是具有高Pe的明显非布朗系统，如果Re很小，也会表现出变化。本文描述了低容器-颗粒尺寸比系统在这种条件下的概率分布和泰勒色散系数，其中效果特别明显，但流动模拟相当困难。我们还确定了参数制度和物理条件需要看到一个实质性的表现效果。
The combined effects of radial drift due to flow inertia and diffusion due to Brownian motion significantly modify the radial probability distribution and the axial dispersion of conduit-bound suspended bodies. This interplay depends on the product of Peclet Pe and Reynolds Re numbers so that even apparently non-Brownian systems with high Pe exhibit the changes if Re is small. This article describes the probability distribution and the Taylor dispersion coefficient under such conditions for systems with low vessel-to-particle size-ratios where the effect is especially pronounced, but the flow-simulation is considerably difficult. We also identify the parametric regimes and the physical conditions required to see a substantial manifestation of the effect.
