The Shape of Rain

In our collective imagination, a raindrop is pendant shaped, wide at the bottom and pointed at the top. But, in fact, a falling raindrop experiences much more complicated shapes.  (Image and video credit: I. Jackiw and N. Ashgriz) Read the full article

Cavitation Near Soft Surfaces

Collapsing cavitation bubbles are sometimes used to break up kidney stones, and they may find other uses in medicine as well. Here, researchers investigate the collapse of laser-triggered cavitation bubbles near tissue-mimicking hydrogel.  (Image and video credit: D. Preso et al.) Read the full article

Tweaking Coalescence

When a drop settles gently against a pool of the same liquid, it will coalesce. The process is not always a complete one, though; sometimes a smaller droplet breaks away and remains behind (to eventually do its own settling and coalescence). When this happens, it's known as partial coalescence. (Image and video credit: T. Dong and P. Angeli) Read the full article

Eroding the Sphinx

One theory suggests that the Great Sphinx of Giza formed -- in part -- naturally as a result of erosion, and ancient Egyptians added features to the bedrock formation. To test the plausibility of the theory, researchers made a miniature sphinx. (Image credit: S. Boury et al.) Read the full article

Billowing Ouzo

Pour the Greek liquor ouzo into water, and your glass will billow with a milky, white cloud, formed from tiny oil droplets. The drink's unusual dynamics come from the interactions of three ingredients: water, oil, and ethanol.  (Image and video credit: Y. Lee et al.) Read the full article

Tornadoes in a Bucket

In nature, some powerful tornadoes form additional tornadoes within their shear layer. These subvortices revolve around the main tornado, causing massive destruction in their wake.  (Image and research credit: G. Di Labbio et al. 1, 2) Read the full article

Predicting Contamination in Urban Environs

The canyons of a city's streets form a complex flow environment. To better understand the risks of a spreading contaminant, researchers simulated a release in lower Manhattan's urban jungle. (Image and video credit: W. Oaks and A. Khosronejad)

Giant Droplet Splashes

When droplets get larger than 0.27 cm, they no longer stay spherical as they fall. Here, researchers look at very large droplets (equivalent to 3.06 cm in diameter) falling into water. (Image credit: S. Dighe et al.)
