Prof Kirby from Cornell University now has started producing videos of his class. Currently he directs the Micro/Nanofluidics Laboratory in the Sibley School of Mechanical and Aerospace Engineering. His research focuses on microbioanalytical devices, nanofiber textiles, nanoscale fluid mechanics, microparticle processing etc. He has also published books on micro- and nanoscale fluid mechanics from Cambridge University press.
In this post, I have put together his class videos on patterning microchannels using laminar flow. Laminar flow is a flow where liquid flows in parallel layers. In micro-channels this kind of flow is found (against turbulant flow in macroscale e.g., in rivers) so that two or more different solutions can flow in the same channel with mixing (only mixing by diffusion). This property of fluid in micro/nano domain can be exploited to pattern these systems. Prof Kirby teaches the theoritical basics of this phenomenon with examples/applications.
In the last video, he discusses about the Low-Re-High-Pe limit constraints for laminar flow patterning in microfluidics.
