Experimental Study and Hydrodynamic Performance Analysis of a Bio-tail Fin Propellant System

摘要

In order to research the bionic mechanics in unsteady flow, this paper mainly focuses on designing an experimental device and setup in analogy to bionic tail fin, so as to investigate the hydrodynamic performance of the oscillating tail fin. The optimization movements of the mechanical tail fin can be obtained by the comparisons of the propulsion efficiency, propulsion coefficient and lateral force coefficient at different conditions.
