Laser-induced deformation and fragmentation of droplets in an array

Droplet-droplet interactions is ubiquitous in various applications ranging from medical diagnostics to enhancing and optimizing liquid jet propulsion. We employ an experimental technique where the laser pulse interacts with a micron-sized droplet causes optical breakdown. The synergy of nanosecond isolated spherical accurately controlled manipulated influence deformation fragmentation array droplets. elucidate how fluid dynamic response (such as drop-drop shock-drop interactions) arrangement droplets can be regulated optimally shaped by energy its interplay density target. A new butterfly type breakup revealed, which found result efficient outer array. spatio-temporal characteristics laser-induced breakdown dictate shock wave central fragments incident width employed this work are representative diverse industrial such surface cleaning, nano-lithography, microelectronics, procedures intraocular microsurgery.
