Peering Into the Gap
This video offers a glimpse into turbulence developing in a classic flow set-up, a Taylor-Couette cylinder. The apparatus consists of two upright, concentric cylinders; the outer cylinder is fixed, and Keep reading
Aerated Faucets
So much goes on in our daily lives that we never see. But with the power of the smartphones in our pockets, we can catch more than ever before, as Keep reading
Fish-Scale Tides
On 31 July 2022, an unusual tidal phenomenon, a fish-scale tide, took place on the Qiantang River’s estuary in Zhejiang Province, China. Here are a couple videos. I’ve not found Keep reading
Groundwater-Structure Interactions
Groundwater can sometimes wind up in unexpected places, given the way it interacts with subsurface structures. In this Practical Engineering video, Grady discusses the paths that groundwater takes around structures Keep reading
Seeing the Flow
Experimentalists often need a sense for the overall flow before they can decide where to measure in greater detail. For such situations, flow visualization techniques are a powerful tool since Keep reading
Reefs Along New Caledonia
Brown reefs edge a turquoise lagoon in this astronaut snapshot of the New Caledonian coastline. Reefs like these form a natural barrier that protects coastlines from storms by breaking up Keep reading
