防除冰过程中的传热传质特性
Mass and Heat Transport During Anti-icing and De-icing Processes
摘要
Abstract
Suppression of ice formation by inhibiting droplet deposition from both passive surface functionalization and active application of ultrasonic vibration is investigated through numerical simulation and experiments.The contact time of droplet impacting on superhydrophobic surfaces with macro-structures,including cubic protrusion,single and crossed triangular ridges,and suspended prism,can be effectively reduced due to the droplet deformation induced by the structures during expansion and retraction processes.The substrate subjected to ultrasonic vibration exhibits a nonlinear distribution of equivalent shear stress,which leads to different dynamics modes of impact droplet and iced droplet removal performance.This work reveals the effectiveness of macro-structures and the ultrasonic vibration on anti-icing and de-icing,and provides potential approaches for the design and optimization of anti-/de-icing system.关键词
