Abstract
En 中文
• Active natural convection control is studied using oscillating flexible fins. • Four forced flexible fins are applied in a square-in-square enclosure. • Fin oscillation disrupts thermal boundary layers and enhances mixing. • Longer and more flexible fins provide stronger overall heat transfer. • Overall heat transfer improves by up to 90% compared with rigid fins.
