- Description
- Flow simulations of jetting of inkjet drops are presented for water and ethylene glycol. In the inkjet printing process, droplet jetting behaviour is the deciding parameter for print quality. The multiphase volume of fluid (VOF) method is used because the interaction between two phases (air and liquid) is involved in the drop formation process. The commercial inkjet printer has a nozzle diameter of ~73.2?m. In this work, a simulation model of inkjet printer nozzles with different diameters 40?m, 60?m, and 80?m are developed using ANSYS FLUENT software. It is observed that when water is taken as solvent then the stable droplets are generated at 60?m nozzle diameter till 9?s because of its low viscosity. For higher diameter, the stamen formation is observed. Ethylene glycol stable droplets are achieved at 80?m nozzle diameter till 9?s because of their high viscosity (~10 times that of water). Along with the droplet formation, the sustainability of the droplet in the air before reaching the substrate is also important. The simulation model is an inexpensive, fast, and flexible alternative to study the ink characteristics of the real-world system without wasting resources. 2022 Institute of Physics Publishing.
