We obtain a numerical solution of the equation for the synchronous unsteady motion of two spherical vesicles in incompressible viscous fluid in the presence of both Stokes drag and hydrodynamics memory. We find that for a given amount of work performed, the final distance traveled by each vesicle is increased by the presence of the other vesicle moving in the same direction. The result suggests that the unsteady transport of the vesicles by molecular motors in vivo may be facilitated due to an effective hydrodynamic interaction between the neighboring vesicles.
我们获得了在不可压缩粘性流体中存在 Stokes 阻力和流体动力学记忆的情况下两个球形囊泡同步非定常运动方程的数值解。我们发现，对于给定的功，每个囊泡最终行进的距离会因另一个以相同方向运动的囊泡的存在而增加。结果表明，由于相邻囊泡之间的有效流体动力学相互作用，体内分子马达对囊泡的非定常输运可能会得到促进。
