在三维非对称势场中数值研究了自推进粒子的定向输运。除了空间排斥力，颗粒之间的流体动力学相互作用已被考虑在一个近似的方式。从数值模拟中，我们发现，流体动力相互作用可以强烈地影响自推进粒子的整流输运。流体动力学相互作用增强了整流传输的性能时，颗粒可以很容易地通过势垒的潜力，并减少整流传输时，颗粒主要是被困在势阱。
Directed transport of self-propelled particles is numerically investigated in a three-dimensional asymmetric potential. Beside the steric repulsive forces, hydrodynamic interactions between particles have been taken into account in an approximate way. From numerical simulations, we find that hydrodynamic interactions can strongly affect the rectified transport of self-propelled particles. Hydrodynamic interactions enhance the performance of the rectified transport when particles can easily pass across the barrier of the potential, and reduce the rectified transport when particles are mainly trapped in the potential well.
