| Abstract: | Piezoelectric ejection, as one of the technology of droplet ejection, has comprehensive application prospect. This paper has established the elementary model of the ejection course of fluid based on the primary principle, and defines the theoretical displacement curve. It also makes the finite element analysis with the fluidic motion of the ejection course, and represents detailedly the impact of cavity dimension and structure parameter and fluidic property to the behavior of fluid. |
