Web6 feb. 2024 · Small drops in moderate turbulence tend to break only once (initial breakup). The interfacial energy of a drop was tracked as a function of time during drop deformation and breakage. The maximum energy level of the deformed mother drop was compared to commonly used estimates of critical energy necessary to break a drop. WebDrop breakup in fluid flows is investigated here as an exchange between the fluid's kinetic energy and the drop's surface energy. http://hs.link.springer.com.dr2am.wust.edu.cn/article/10.1007/s41116-020-00025-6?__dp=https horseshoe shaped tunnel
