Flow Control of Nano Fountain Pen Using Active Membrane Pumping

In this paper, flow control of nano fountain pen using active membrane pumping is investigated. This FPN has been integrated with pumping chambers, micro channels, and a high capacity reservoir for continuous ink feeding. The control of fluid injection using active membrane pumping in chambers is the answer of the problem. The flow rates in channels with the presence of capillary force are theoretically analyzed, including the cantilever deflection and the control of mass flow rates by deflection of membrane. Then, the above results are compared with numerical results based on the commercial code, FLUENT
