India. ABSTRACT A majority of the modern inkjet printers utilise drop on demand devices because of its precision in terms of time and easy control. The time-dependent fluid interface disruption renders the fluid dynamics process during droplet ejection complex. The current work attempts to provide an idea of the drop ejection behaviour based on the computation of energies required for droplet formation and splat formation. The simulation results for various nozzle diameters with different polymer inks are examined and it is validated with computational model. Further attempt is made to analyse the effect of rheological properties like viscosity and surface tension in the droplet formation. Key words Drop on demand inkjet droplet ejection viscosity surface tension.
