仿生鳍形状与运动模式对推进性能的影响
Effect of Shape and Motion Patterns on Propulsion Performance of Biomimetic Fin
摘要
Abstract
In order to illustrate the inner relationship between shape and motion patterns of the biomimetic fin, the unsteady incompressible N-S equation and continuity equation were solved by an uncoupled implicit solver.The forces generated from four kinds of fin shapes ( diamond, square, rectangle and triangle ) in undulating and oscillating propulsion patterns under the same kinematic parameters and area were analyzed. From aspects of the pressure distribution and the structure of vortex street, the reasons of the differences were presented, the inner relationship between the fin shape and propulsion mode was also illustrated.The results show that the different propulsion modes have different propulsion forces when the kinematics parameters and fin shapes are the same.Similarly, when the same kinematic parameters and propulsion modes are used, the fin shapes have a great influence on propulsion forces.The study provides a reference for the selection of suitable fin shape and matching propulsion mode for bionic fish thrusters to achieve better propulsion performance.关键词
