Abstract
En 中文
• Vapor separation structure effectively suppresses these ultrasound-induced penalties. • Synergy achieves PEC of 1.75 and broadens high-efficiency heat flux range. • Upstream nucleation and downstream separation enable coordinated performance gains. • Ultrasound enhances heat transfer at the cost of pressure drop and instability.
