Ultra-High Speed Particle Image Velocimetry on Drop-on-Demand Jetting
(Proc 27th Int. Conf. on Digital Printing Technologies NIP27, 2011)
An experimental setup to study the dynamics of droplet jetting from a commercially available print-head is described. A MicroFab print-head with an 80 µm
diameter transparent nozzle was set to print droplets at a speed ...
The dynamics of the impact and coalescence of droplets on a solid surface
(Biomicrofluidics, 2011)
A simple experimental setup to study the impact and coalescence of deposited droplets is described. Droplet impact and coalescence have been investigated by high-speed particle image velocimetry. Velocity fields near the ...
Holographic Measurement of Drop-on-Demand Drops in Flight
(Proc 27th Int. Conf. on Digital Printing Technologies, NIP27, 2011)
The analysis of images of ink drops in flight can provide information about jet straightness, drop velocity and volume.
However trade-offs between field of view, optical and digital resolution and other factors such as ...
