  • Modelling of resonant droplet detachment in laser metal droplet generation [Elektronski vir]
    Jeromen, Andrej, 1975- ; Govekar, Edvard
    In laser generation of droplets from a metal wire, it has been observed experimentally that droplet detachment can be influenced by interaction of the laser pulse frequency and eigen dynamics of a ... pendent droplet. In laser pulse frequency range between 70 Hz and 150 Hz, the dynamics of the pendent droplet resembles that of a spring-mass system. Based on experimental observations a nonlinear model of droplet generation in the form of spring-mass oscillator is developed. Model based simulation of pendent droplet dynamics, and especially predicted time of droplet detachment and detached droplet diameter are in high agreement with experimental results.
