Flow visualization is the process of making the physics of fluid flows (gases, liquids) visible. This site is devoted to a course for mixed teams of engineering and fine arts photography and video students at the University of Colorado. In this course, we explore a range of techniques for creating images of fluid flows. Our work is motivated not just by the utility and importance of fluid flows, but also by their inherent beauty. Flow visualization is for everybody: if you have paid attention to the patterns while stirring milk into coffee or stared at the curl of a rising tendril of smoke you have participated in flow visualization. Art and science are similar in that they both thrive on deep seeing, on expanded perception and attention, which can be gained through simple experience. Everyone is capable of this. Spend some time noticing flow visualization around you and you’ll find your life is richer. Please explore this site; there are resources for teachers and students of all levels, as well as amazing images that anyone can enjoy.

Galleries

Yay, all student work is finally up! I’m in the process of categorizing and tweaking recent work (2018 to 2016), and then I’ll get to updating earlier work.

Old galleries, from 2003 to 2012 in the original html format (not great for mobiles, sorry) and new, 2013 to present (fully responsive!)

Flow Vis Collection

In honor of the American Physical Society Division of Fluid Dynamics 70th Annual meeting a collection of Flow Vis work spanning the entire history of the course was projected on the Grand Concourse at the Colorado Convention Center, November 19-21, 2017. The collection is available online in two parts: Part 1 and Part 2

Post your Flow Vis web finds for others to enjoy: Flow Vis Facebook Group.

Videos on Vimeo

Old and new student videos are being posted on Vimeo too, in the Vimeo Flow Visualization Student Work Channel and anybody can join and add to the Flow Visualization Vimeo Group.

Try it yourself!

Here are two modules developed for middle schools:
Floating and Falling Flows illustrates some physics of buoyant plumes
The Density Rainbow and the Great Viscosity Race illustrate the fluid properties of density and viscosity.
Comments on how these experiments worked for you are welcome. Email us.

Flow Visualization Traveling Show, No Longer Traveling:

Fifteen images are now on permanent public display in the Jennie Smoly Caruther Biotechology Building cafe at CU Boulder. Curated by Prof. Jean Hertzberg (CU Boulder) and Carla Selby (Tesseract Productions), with support from the Boulder Arts Commission. You can download a flyer, or preview the show here.

If you would like to host a display of flow vis images for local printing or projection we can arrange access to the collection; contact Prof Hertzberg.
