双面均匀分布藤壶对螺旋桨尾迹动力学影响研究
Study on the impact of double-sided evenly distributed barnacles on propeller wake dynamics
摘要
Abstract
To accurately evaluate the influence of marine biofouling on propeller wake dynamics,this paper adopts the improved delayed detached eddy Simulation(IDDES)method.Based on 50.7 million unstructured grid cells,it systematically investigates the mechanism of double-sided uniformly distributed barnacles on the propeller wake evolution,vortex structure instability and hydrodynamic performance.The results show that barnacle attachment significantly changes the topological morphology of tip vortices and induces shedding vortices with an opposite rota-tional direction to the tip vortices.The strong shear mutual inductance triggers the short-wave instability of the wake in advance and accelerates the collapse of the vortex system and energy dissipation.After attachment,the thrust coefficient of the propeller is reduced by 63.98％,the torque increased by 17.76％,and the open water effi-ciency decreased by 69.41％.This paper reveals the physical mechanism by which barnacles degrade propulsion performance through wake dynamics,providing a theoretical basis and numerical support for the antifouling preven-tion,operation optimization and efficient antifouling strategies of marine propellers.关键词
