Investigation of water droplets climbing up hot saw blades
| Challenge: | International | | Category: | Junior | | Region: | Taiwan, R.O.C. | | City: | Taichung City, | | School: | | | 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. |
