仿生鱼游动的耦合水动力
Coupled hydrodynamics of bionic fish swimming
摘要
Abstract
In this study,a three-dimensional bionic fish model was established to investigate the coupled hydrody-namic mechanisms between the fish body and fins.Numerical simulations of fish swimming were conducted using a partitioned hybrid mesh and dynamic mesh technology.The results indicate that the fish body enhances thrust gen-eration by the caudal fin while reducing power consumption and that the dorsal fin further decreases body resis-tance.A smaller wave number facilitates high-speed propulsion,whereas a larger wave number is more suitable for efficient cruising.Increasing the amplitude of the caudal fin oscillation improves thrust but also raises power con-sumption.Therefore,this study aims to provide a control strategy support for the design of highly efficient underwa-ter robots.关键词
