High Speed Color Schlieren Imaging

Best of Web // Alex Smith

Depicted here in brilliant color and detail using high-speed Schlieren imaging are bubbles as they collapse after impact from a particles. The spherical geometry of a bubble is due to the natural tendency toward an even distribution of the lowest possible surface tension. Once damaged the membrane rapidly recedes from the point of impact converting the liquid film into tiny droplets. Even the boundary layer of flow around the incoming particle can be seen distorting the bubble’s shape prior to collision.

These videos were produced out of MIT’s Edgerton Center by a team of professors as a part of their high speed imaging courses. A rubber tube loaded with Glycerin was used to produce the bubbles while ultra slow-motion video was captured using a color Schlieren technique.

    First prize for best of web. The dynamics of the collapsing bubble caught in slow motion combined with the coloring in the scene makes this video scientifically interesting as well as aesthetically amazing.

    1st Prize for best of web. This video does a great job of visualizing the surface tension around a bubble. Once the olive disrupts the membrane the surface tension is broken and the bubble ruptures. Using the slow motion camera allows for a incredibly in depth look at each part of the process. The choice of background adds a very vibrant and large range of colors. I also think the choice of music in the video creates a nice atmosphere.

    First prize for BOW. This is a really great slow-motion video, that is wonderfully done. Super great use of Schlieren imaging and I really enjoyed the contrast with the colorful background.

    1st for best of web. This was a fascinating video to watch. I really enjoyed seeing such a rapid phenomenon happen slowly and in such high resolution. The high speed imagery alone is astounding.
    I also liked the beautiful array of colors in these images. The colors and lighting allow the fluid motion on the bubble, before it ruptures, to be visible. Then, after the bubble is ruptured, we are able to clearly see the motion of the collapsing membrane. Afterwards, we can see the motion of the remnants of the bubble move in interesting patterns. It is mesmerizing.
    (I also like that some of the particles look like green olives)
