对悬浮在二维流中的刚性粒子通过分叉通道的运动进行了数值计算。计算的颗粒轨迹取决于分叉处总体积的分配、颗粒相对于通道尺寸的尺寸以及颗粒的上游横向位置。结果用于推断进入分叉的每个分支的稀悬浮液中的颗粒通量，作为进入每个分支的总体积流量的函数。计算结果显示了在毛细血管分叉处红细胞通量的实验数据中观察到的几个定性特征。
The motion of a rigid particle suspended in a two-dimensional flow through a bifurcating channel is calculated numerically. The calculated particle trajectories depend on the partitioning of total volume at the bifurcation, the size of the particle relative to channel dimensions, and the upstream lateral position of the particle. Results are used to deduce the flux of particles in a dilute suspension entering each branch of a bifurcation as a function of the total volumetric flow entering each branch. The calculated results exhibit several qualitative features observed in experimental data for red cell flux at capillary bifurcations.
