Abstract: This paper designed a diffuser-augmented flapping wing device. Based on the orthogonal experimental design and numerical method, it is aimed to simulate the impact of structural parameters on the power coefficient and energy harvesting efficiency and research the effect and prioritize of structural practices on flapping wing performance. The results show that the energy harvesting efficiency can be improved by 53.7% by selecting appropriate parameters. The performance of the power coefficient is sensitive to the variation of flange height and diffuse angle, and the efficiency is sensitive to the variation of inlet spacing and flange height. Besides, the energy efficiency of the diffuser-augmented flapping wing will be improved under unsteady upstream velocity.
