摘要:
针对目前并联扑翼装置采集性能优化手段单一、提升效果不佳的问题,提出并联扑翼非对称振荡模式。采用动网格技术,建立一套非对称振荡模式下并联扑翼振荡控制与仿真程序,实现对多种复杂非对称俯仰振幅振荡过程的准确模拟,揭示多种非对称冲程下并联扑翼的能量采集性能及气动特性变化规律,阐明并联扑翼附近的涡结构与压力场演变规律。研究表明,随着俯仰振幅增大,扑翼平均功率系数及采集效率均呈现先增大后减小的趋势,验证了通过非对称振荡模式有效提升并联扑翼装置性能的可行性。
Abstract:
To solve the problem of the inefficient optimization methods and the poor performance improvement on parallel-foil device , the asymmetric oscillation modes of parallel foils were put forward. Based on the dynamic mesh technique , the asymmetric oscillation control and simulation code of parallel foils was established.The accurate simulations at diverse complex asymmetric pitching amplitude oscillations were realized.The rules of the energy extraction performance and the aerodynamic characteristics of parallel foils at diverse asymmetric strokes were concluded.The evolution rules of the vortex structure and the pressure field near parallel foils were illustrated.Results show that the average power coefficient and the extraction efficiency increased first and then decreased with the increasing pitching amplitude.It is proved that using the asymmetric oscillation mode to improve the performance of parallel foils is feasible.
