Experimental investigation of droplet breakup of oxide-forming liquid metals

T Hopfes, Z Wang, M Giglmaier, NA Adams - Physics of Fluids, 2021 - pubs.aip.org
This work investigates the breakup of liquid metal droplets experimentally using a shock
tube. Droplets of Field's metal melt are produced and their flow-induced deformation and
rupture are captured by a high-speed camera. Results are compared to previous data on
Galinstan droplet breakup using image sequences and deformation data. Regarding
differences, we find that Field's metal droplets show slightly larger deformations and breakup
into a larger number of smaller fragments, especially at low Weber numbers. We expect this …
