We study the mixing of active swimmers. Two different types of swimmers (modeled as particles) are placed initially in two boxes with an interconnection between them. The mixing of swimmers happens as they move with their own self-propelled forces. The self-propelled force is constant and the direction of the exerted thrust is governed by the neighboring swimmers. Overall mixing of the swimmers depends on the magnitude of the exerted thrust, the initial packing fraction, and the activity level. Different nonequilibrium states are also identified depending on the exerted thrust and the initial packing fraction of the swimmers.
我们研究了活性游泳者的混合。两种不同类型的游泳者（模拟为粒子）最初被放置在两个盒子中，它们之间有一个连接。游泳者的混合是由于它们在自身推进力的作用下移动而发生的。推进力是恒定的，施加的推力的方向由相邻的游泳者决定。游泳者的整体混合取决于施加的推力的大小、初始堆积分数和活动水平。根据施加的推力和游泳者的初始堆积分数，还确定了不同的非平衡状态。
