Initial computational research on an undulating-finned robotic fish
In this paper, a prototype of biologically inspired robotic fish is developed which has a novel mechanical fin structure conceived and designed to be as the propulsion part. The ultimate goal of this project is to provide an insight into the methodology of designing and controlling a propulsion system underwater, which is employed at low speeds, offering greater maneuverability, better propulsive efficiency. To analyse the force acting on the surface of the fin, a two-dimensional unsteady Computational Fluid Dynamics (CFD) method is used for better understanding the fluid mechanism during the undulation of the mechanical fin. An unstructured, grid-based, unsteady Navier-Stokes solver is used to compute the unsteady flow around the fin and the ? pressure distribution on the fin surface. Finally, experiments are performed to test performances of the fin and to verify the feasibility for further development as an alternative propulsion method for underwater vehicles.
