所有的好东西都是三个-三个珠子学习与晶格玻尔兹曼和刚体求解器游泳
All good things come in threes - Three beads learn to swim with lattice Boltzmann and a rigid body solver
摘要：
我们模拟了在低雷诺数的制度中的流体中的设备的自推进。每个装置由三个与两个阻尼谐波弹簧连接的主体（球体或胶囊）组成。正弦驱动力压缩在刚体物理引擎内解决的弹簧。后者是一贯耦合到一个三维格子玻尔兹曼框架的流体动力学。在三球装置的模拟中，我们发现推进速度与理论预测吻合得很好。在模拟中，一些或所有的球体被替换为胶囊，我们发现，设计的不对称性强烈影响推进效率。
英文摘要：
We simulate the self-propulsion of devices in a fluid in the regime of low Reynolds numbers. Each device consists of three bodies (spheres or capsules) connected with two damped harmonic springs. Sinusoidal driving forces compress the springs which are resolved within a rigid body physics engine. The latter is consistently coupled to a 3D lattice Boltzmann framework for the fluid dynamics. In simulations of three-sphere devices, we find that the propulsion velocity agrees well with theoretical predictions. In simulations where some or all spheres are replaced by capsules, we find that the asymmetry of the design strongly affects the propelling efficiency.
