and biological reagents and capable of performing a variety of “digital fluidic” operations that …

Physics of liquid jets

J Eggers, E Villermaux - Reports on progress in physics, 2008 - iopscience.iop.org
Jets, ie collimated streams of matter, occur from the microscale up to the large-scale
structure of the universe. Our focus will be mostly on surface tension effects, which result …

Transition from squeezing to dripping in a microfluidic T-shaped junction

M De Menech, P Garstecki, F Jousse… - journal of fluid …, 2008 - cambridge.org
We describe the results of a numerical investigation of the dynamics of breakup of streams of
