Abstract

Prionace glauca has high efficiency and long-distance cruising mode, its pectoral fins play an important role in keeping balance and stability. Selecting the pectoral fins as a breakthrough to conduct related research has an important value for the optimization design of autonomous underwater vehicle (AUV) and other marine equipment. Through numerical description, the establishment of a two-dimensional fine pectoral model and finite element calculations in the unsteady fluid, we found the variation features of Karman Vortex Street of flexible pectoral fins in the unsteady flow. Further comparative analysis of vortex characteristics of Prionace glauca pectoral fins models with different shapes and under the same boundary conditions, the study found that the streamlined samples of pectoral fins help reduce the impact of water flow and improve the stability of Prionace glauca during swimming in the flow field, which provides a good foundation for structural optimization design and other related applications of AUV.
