摘要/Abstract

摘要：

以滑波推进器为原型，基于RANS方程，采用动网格技术计算了6翼异步拍动翼串列时的水动力性能，探讨了来流、摆幅角、翼间距、运动周期和升沉幅度等对其推进性能的影响，并建造样机.计算结果表明，串列异步拍动翼不同位置翼表现出不同的性能，且任一位置翼比单片异步拍动翼产生更大的推力.尾涡分析表明，翼间涡系干扰是不同位置翼性能不同的主要原因，且其干扰对推力的产生有利，小间距时可产生更大推力.

Abstract:

The hydrodynamic performance of 6 tandem asynchronous flapping foils (TAFFs), referring to the Wave Glide propulsor, was calculated based on the RANS equations by adopting the dynamic mesh method. The relationship between the freestream velocity, flapping angle, distance between TAFFs, active period and flapping amplitude were investigated and a prototype was built. The results show that TAFF represents different performances at different locations. TAFF can produce higher propulsion than a single asynchronous flapping foil. The characteristics of the wake were analyzed and the reason for TAFF’s different performance was found to be the interaction between TAFF’s wake which was advantageous for propulsive. It can produce higher propulsion when the distance between TAFFs is shorter.

Key words: tandem asynchronous flapping foil(TAFF), propulsion performance, vortices intersection； dynamic mesh
