Two-Phase-Flow Simulation of Dynamic Inkjet Droplet

CHAO Chung-hsing;Department of Mechatronic Engineering,Ta Hwa University of Science and Technology;  
In this study,the generation of an inkjet droplet upon a wetted flat solid surface was numerically simulated to determine the key to generating the droplet.A computational fluid dynamics model,based on the volume of fluid(VOF) method,was set up to simulate the droplet process on the wetted flat solid surface,in which surface tension and wall adhesion were taken into account.The results show that the VOF-based model can be used to simulate the dynamics of the droplet upon a wetted solid surface,and it can reflect the interaction between dynamic droplet and the wetted solid surface and some main characters.This Simulation is useful to improve the understanding of the fluid flow,and can predict the optimal design of an inkjet for a specific application.
