Hydrodynamic analysis of the pectoral-fins in viscous flows

This paper presents two-degree-of-freedom and three-degree-of-freedom motion models established for a rigid pectoral fin.FLUENT software as RANS solver and the methods of dynamic mesh and post-processing system of the FLUENT software were fully employed.Thrust characteristics have been calculated based on the motion model.Numerical results are compared with recent experiment's results in detail in this paper.The study reveals that the unique surface pressure distribution and the change mode of the tail vortex are the main factors for the pectoral fin's high thrust efficiency.
