水下拍动翼塔筒尾涡能量捕获数值模拟研究
Numerical Study on Energy Capture from Tower Wake of Underwater Flapping Wings
摘要
Abstract
The flapping foil,as a simplified model for energy extraction study,converts tidal energy into electrical output.While its behavior under uniform flow is well-studied,complex flow conditions with unsteady vortices require further investigation of NACA0015 airfoil under cylinder wake effects.Using CFD simulations,hydrodynamic characteristics and energy harvesting efficiency under various motion parameters are studied.Furthermore,vortex structures and the effects of pitching and heaving amplitudes are analyzed.The results show that energy capture efficiency increases with heaving amplitude,while cylinder wake effects decrease with larger pitching amplitude.The analysis provides a reference scheme for efficient tidal energy collection in offshore wind farms,contributing to both improved efficiency and reduced tower vortex-induced vibrations.关键词
