Investigation of water droplets climbing up hot saw blades
Region:Taiwan, R.O.C.
City:Taichung City,
Abstract:Water droplet climbing up stacked saw blades with asymmetric saw tooth profile has been investigated. The climbing occurred at temperature about 400℃ with the incline up angle depending on the droplet's size. The driving forces are associated with the vapor pressure and recoiled momentum due to water evaporation.
