| Abstract Scope |
Tailings are produced by high-titanium blast furnace slag using "high-temperature carbonization-low-temperature chlorination" technology. In this paper, droplet impact on a heated tailings surface is experimentally investigated over a wide range of Weber numbers and surface temperatures. The spreading of droplets into a liquid film on the tailings surface and dynamics behaviors of the droplets were observed using a high-speed camera. Five regimes are observed, namely spreading, boiling induced break-up, advancing recoiling, splashing with continuous liquid film, splashing with broken liquid film. In addition, the effects of Weber number and surface temperature on boiling mode and droplet spreading are examined. The scaling law of maximum spreading ratio with the impact Weber number is also established, and agrees well with experimental measurements and the literatures over a range of Weber numbers and high temperature. |
