Colourful fluid dynamics
September 16, 2010 9:38 AM   Subscribe

Two galleries of fluid motion - one from the journal Physics of Fluids, and one from MIT. The MIT gallery shows some common everyday fluids in unexpected lights. The PoF gallery (which is quite extensive, check out the 85-09 archives) mostly concerns itself with more esoteric interests. Some of the results presented have a stark beauty and some are riotously colourful. I personally love the results that look at turbulence and transition. Also, some visualisations from the past ten or so years are presented as video! (PDFs, Quicktime)

I enjoy a nice droplet pinch-off every now and again.

When a vertical water jet strikes a circular horizontal impactor...that's amore!

If I were very rich, I would pay these scientists to let me sit in their lab and watch them take these pictures while I ate mushrooms.

Seriously neat.

For more fluid experiment stills in book form, I recommend Van Dyke's An Album of Fluid Motion.

Every time I come across this subject, I'm taken back to my undergrad and grad fluid mechanics courses and the old, very worn VHS videos we would watch, presented by some of the giants in the field. Back then, I couldn't manage to find where I could acquire copies for myself but it just so happens that someone's posted them to Youtube. So, enjoy:

Flow Visualization: Part 1, Part 2, Part 3
(IIRC, there's a neat experiment in there showing that the Coriolis forces acting on water being drained from a tank are much weaker than most people think)

Low Reynolds Number Flow: Part 1, Part 2, Part 3, Part 4
(see in particular the bit about reversible flow if you really want your mind blown)

Oh, man. Look under the mattress of any teenaged faucet and you'll find water-stained inkjet printouts of those photos in the MIT gallery.

There's also book entitled A Gallery of Fluid Motion, which collects images from the "Gallery of Fluid Motion" articles in Physics of Fluids, which was inspired by Van Dyke's book.
