Abstract
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.
