Abstract

Abstract

En 中文
• Experimental study of FIV-based energy harvesting in tandem square cylinders. • Cylinder size ratio and spacing strongly affect galloping response. • Wake interference boosts displacement by 356.5% and voltage by 171.9%. • CatBoost ML accurately predicts flow–structure–power coupling. • Hybrid experimental–ML approach supports flow-adaptive energy harvesters.
