This study explores the potential effects of aerodynamic parameters on performance galloping piezoelectric energy harvester. By considering geometric configurations, a bluff body cross-sectional shape evolution approach is proposed using Boolean operations polygons and forty-eight different shapes with protruding depressed features are considered. Computational fluid dynamics employed to perform time-varying simulation characteristics. The investigated computationally distributed parameter electromechanical coupling model. critical wind speed, maximum output power, slope power versus speed curve introduced as evaluation parameters. results show that rear-side feature top-side bottom-side have significant enhance performance. Furthermore, symmetrical structure in downstream direction should be prioritized over asymmetric designs.
