Lattice Boltzmann Simulation of Laser-induced Transfer of Liquid
The mesoscopic lattice Boltzmann method and the gas-liquid two-phase flow model are used to simulate the Laser-induced Forward Transfer (LIFT) of liquid. Rayleigh-Plesset equation is introduced to calculate the evolution of the plasma bubble, so as to obtain the inlet boundary conditions for the two-phase LBM model of the LIFT. The simulation results agree well with former experimental observations. The evolution of bubble shape, the forward and backward ejections are all faithfully represented, which suggests that the dynamics of the laser-induced bubble is mainly responsible for the material transfer in LIFT. The forward liquid ejection is related to the fast expansion of the laser-induced bubble, while the backward ejection is caused by the collapse of the bubble.
