초록
Numerical models of fluid dynamics inside the micro actuator chamber and nozzle are presented. The models includeink flow from reservoir, bubble formation and growth, ejection through the nozzle, and dynamics of refill process. Since hightapered nozzle is one of the very important parameters for overall actuator performance design. The effects of variations ofnozzle thickness, diameter, and taper angles are simulated and some results are compared with the experimental results. It isfound that the ink droplet ejection through the thinner and high tapered nozzle is more steady, fast, and robust.
