The deposition of frost/ice is inevitable and negatively impacts many fields and industries, such as the frosting of air source heat pumps and liquid natural gas vaporizers, and icing of aircraft and power cables. On the other hand, ice slurry is widely deployed for cold storage and transportation of food and organs. To accurately predict and control the frosting/icing process, this project aims to study and understand the interrelated heat, mass and momentum transport phenomena of water droplets from condensation to defrosting. Outcomes of this project should contribute to the development of new material, such as applicable anti-icing/anti-frosting surfaces, and relative technology and equipment, and thus benefit a number of fields.

霜/冰的沉积是不可避免的，并且对许多领域和工业产生负面影响，例如空气源热泵和液化天然气蒸发器的结霜，以及飞机和电力电缆的结冰。另一方面，冰浆被广泛用于食品和器官的冷藏和运输。为了准确地预测和控制结霜/结冰过程，本项目旨在研究和理解水滴从凝结到凝结的相互关联的热量、质量和动量传输现象。该项目的成果将有助于开发新材料，如适用的防冰/防霜表面，以及相关技术和设备，从而使许多领域受益。
