Abstract

This paper quantitatively examines the underlying thermodynamics behind split fire pulse timings. It is shown that there is a direct relationship between the properties of the superheated boundary layer at the onset of bubble nucleation and the experimental data. An application specific - finite element program is shown to predict the jetting response curves with a 0.92 correlation coefficient. The theoretical analysis is robust enough to accurately predict the jetting response for varying pulse trains on two vastly different print head designs. Finally, it is shown that the maxima of the jetting response curves versus time are fundamentally related to the thermal diffusivity of the thin films.
