Rim destabilization and re-formation upon severance from its expanding sheet
M. Kharbedia, B. Liu, R. A. Meijer +4
Upon radial liquid sheet expansion, a bounding rim forms, with a thickness and stability governed, in part, by the liquid influx from the unsteady connected sheet. We examine how t…
Singular jets in free-falling droplets
M. Kharbedia, H. Franca, H. K. Schubert +3
We report on singular jets in a free-falling liquid tin droplet following nanosecond laser-pulse impact. Following impact, the droplet (with diameter or 70\,m) undergo…
Laser-driven droplet deformation at low Weber numbers
M. Kharbedia, H. L. França, H. K. Schubert +3
We investigate droplet deformation following laser-pulse impact at low Weber numbers (We ~ 0.1-100). Droplet dynamics can be characterized by two key parameters: the impact We numb…
Laser-induced droplet deformation: curvature inversion explained from instantaneous pressure impulse
Hugo França, Hermann Karl Schubert, Oscar Versolato +1
We investigate the shape of a tin sheet formed from a droplet struck by a nanosecond laser pulse. Specifically, we examine the dynamics of the process as a function of laser beam p…
