摘要

在本文中，我们研究了人工（机器人）游泳者的起伏刚性鞭毛运动，其连接处由致动器控制。我们采用沉浸边界玻尔兹曼网格法（IB-LBM）对带有起伏刚性鞭毛的游泳者在由两面防滑壁夹住的二维通道内的运动进行了数值分析。为了计算高雷诺数下的流场，采用了多松弛时间（MRT）方案。我们的数值结果表明，最佳雷诺数可使运动距离最大化，而在低雷诺数和高雷诺数限制下，运动方向可能相反。

Artificial swim by undulating rigid flagellum with joint controllers

In this paper, we investigate locomotion of the artificial (robotic) swimmer by the undulating rigid flagellum, whose joins are controlled by actuators. The locomotion of the swimmer with the undulating rigid flagellum inside the two dimensional channel sandwiched by two non-slip walls is numerically analyzed using the immersed boundary Lattice Boltzmann method (IB-LBM). In order to calculate the flow field under the high Reynolds number, multi-relaxation-time (MRT) scheme is applied. Our numerical results show that the optimal Reynolds number exits to maximize locomotion distance, whereas the direction of locomotion can be reversed in the low and high Reynolds number limits.
