Numerical simulation of droplet formation of piezoelectric ink-jet printing

摘要

The thesis adopts the numerical simulation method to simulate the formation and fall of water droplets from the nozzle exit. The numerical model is established based on piezoelectric inkjet theory, then the simulated results are analyzed which includes several stages in the entire course of droplet's motion. The result indicates numerical simulation is suitable for researching the formation and fall of droplets and can provide a good basis for predicting the quality of ink-jet printing.
