A 3-D Karman vortex street behind a cylinder in water seeded with gravity fed dye injection into the wake. Experiment conducted on the ITLL flume.
An inverted image (negative) from the same series:

Very very cool. The edited image and how you made it look like flames, awesome! the contrast and focus are truly exceptional.
Wow! This is by far my favorite out of the Von Karman flows. Especially how the photo was edited to create a flame image. Very Beautiful.
Very interesting setup. Great explanation. I like how you added a second photo with different editing to see more of the physics behind the fluid flow.
Really cool setup. The contrast is magnificent. Focus is superb and the image shows the effect really well. Excellent job.
Great images! Nice job getting a really difficult phenomenon. There is good contrast between the white background and the injected dye, and the shedding behavior is clear and really makes the image.
Wow, stunning. You guys put a ton of effort into this picture, its impressive! I think its very interesting how the negative is so similar to a flame.
– Cool photo, I really like the negative looks like turbulent flames coming out from the sun.
– Great use of resources and understanding of the physics behind it.
Very awesome picture! Amazing focus. All the details, the twists of the vortexes, it looks like smoke almost. Love the simplicity.
This image has cool color, and I like the solid white background. Some of the color on the right edge looks overexposed and details lost, but that might just be due to the mixing.
Really great focus on the dye in the wake. All your hard work at the flume paid off!
So beautiful! Great contrast and color. The focus is great
Wow! amazing image, the contrast between the background and fluid flow is fascinating. The fluid flow is very mesmerizing with the blue dye.
Wow! Nice image! The fluid flow is really crisp, well represented. Nice!
Great image, the white background is a great contrast with the von Karman vortex. A very unique flow that isn’t seen very often.
I really enjoy the inverted image as it gives a different story and it reminds me of juggling fire. I really like your work here you’ve done a fantastic job in capturing a unique image to this course.
Awesome visualization of this fluid phenomena. The bright white background gives this image a great contrast range and makes the blue very vibrant. Nice setup and capture!
Great picture that shows turbulent flow across the cylinder. Very cool processing.
