Numerical Analysis of Nonlinear Deformation and Breakup of Slender Microjets with Application to Continuous Inkjet Printing

摘要

We present a model for predicting the instability and breakup of modulated microjets, and we discuss applications of the model to high-speed inkjet printing. The model is based on a one-dimensional slender-jet analysis and takes into account the coupled thermal/fluidic behavior of the jet. We solve the nonlinear slender jet equations using the method of lines to predict the free-surface, velocity and temperature along the jet. We apply the model to study high-speed continuous inkjet printing.
