Drop Speeds from Drop-on-Demand Ink-Jet Print Heads Article (PDF Available) in Journal of Imaging Science and Technology 57(1) June with 1, Reads How we measure 'reads' Oscillatory incompressible fluid flow with a free surface occurs in an inkjet print head.

Due to complex physical fluid behavior, numerical simulations have been a common approach to characterize the pressure and velocity development in time and :// The operation of a piezo inkjet printhead involves a chain of processes in many physical domains at different length scales. The final goal is the formation of droplets of all kinds of fluids with Droplet generation process can directly affect process regulation and output performance of electrohydrodynamic jet (E-jet) printing in fabricating micro-to-nano scale functional structures.

This paper proposes a numerical simulation model for whole process of droplet generation of E-jet printing based on the Taylor-Melcher leaky-dielectric model. The whole process of droplet generation is The rheological characterisation of linear viscoelasticity for ink jet fluids using Piezo Axial Vibrator (PAV) and Torsion Resonator (TR) rheometers.
