文摘
- •
An experimental system of frost deposition on cryogenic-temperature surfaces was set up.
- •
Liquid air was first formed on cryogenic-temperature surface before frost crystals appeared.
- •
Frost crystal clusters deposited on liquid air droplets are not static, they keep moving.
- •
Under very low surface temperature, as surface temperature drops, the frost layer thickness decreases.
