Ultra-High Speed Particle Image Velocimetry on Drop-on-Demand Jetting
| Description | The project explored the challenges involved in attempting to use inkjet printing methods togenerate small drops of a viscous liquid such as a molten glass. Methods investigated included electrostatic droplet generation (so-called electrospray) as well as capillary breakup of a continuous liquid jet with an external gas sheath. Major outputs from the project were: an understanding of the precise conditions within a wide parameter space under which a discrete cylindrical jet of liquid will break up into multiple drops; and experimental confirmation for the first time of the way in which the neck of fluid between a liquid filament and a drop collapses. These results, which have been published in high-impact scientific journals and also received some press attention, are widely applicable in understanding the behaviour of liquid jets and drops in many applications. They are thus relevant in the biological field (e.g. in some animal defence and attack mechanisms) as well as in geology (the formation of fine lava filaments from volcanos), fluid engineering (e.g. fuel atomization and crop spraying) and materials processing (e.g. material atomization and paint spraying). A further important output from the project has been the development of a novel method of generating liquid drops which is currently being evaluated for patent protection. The method has some significant advantages over conventional methods of operation for inkjet print-heads and will be the subject of further publications. |
