| 中文摘要 | The dynamics of drop-on-demand (DoD) droplet formation and subsequently impact on the solid substrate are investigated using a three-dimensional (3-D) multirelaxation-time (MRT) pseudopotential lattice Boltzmann (LB) model. The wettability of nonideal nozzle plate and solid substrate is modeled by a geometric scheme within the LB framework. The dynamics of droplet formation are explored in a range of the inverse of Ohnesorge number Z=4.95, 11.57, and 28.17, and the Reynolds number Re=39.6, 58.9,, and 136.4. For Z=4.95, no satellite droplet is observed and the wettability of nozzle plate greatly influences the velocity and length of jetting fluids. For Z=11.57, the filament breakup and recombination are observed. The moment of filament breakup is delayed with advancing contact angle For θAincreasing. For Z=28.17 with Re=136.4, the primary and satellite droplets could not be recombined with θA=30º and θA=90º which agree with the literature. Whereas with θA=90º, the recombination occurs. The dynamics of subsequent oscillating droplet impact on the substrate are similar to that of equilibrium droplet which could obtain high-resolution printed features. Consequently, considering θA=90º with large Z and Re numbers, the printable range could be extended which could help increase the printing frequency and boost the production outputs of inkjet printing. |
