Axisymmetric 'spike waves' far exceed limits previously thought to dictate maximum height of ocean waves

In a new study on ocean wave breaking, researchers have demonstrated that the breaking behavior of axisymmetric "spike waves" is quite different to the long-established theories on the breaking of traveling waves.

Mechanical engineers develop ways to improve windfarm productivity

You've probably seen them, perhaps on long roadtrips: wind turbines with enormous, hypnotic rolling blades, harnessing the clean power of wind for conversion into electric energy. What you may not know is that for the explosion ...

Improving bloodstain pattern analysis with fluid dynamics

Often left on the surfaces of a crime scene or on the clothes of an accused criminal, blood backspatter can be used as evidence for forensic scientists to reconstruct what occurred. However, the fluid dynamics at play are ...

Chasing the black holes of the ocean

According to researchers from ETH Zurich and the University of Miami, some of the largest ocean eddies on Earth are mathematically equivalent to the mysterious black holes of space. These eddies are so tightly shielded by ...

New model provides real-time, more accurate prediction of tsunami wave patterns

On January 15, 2022, the Hunga Tonga-Hunga Ha'apai volcano in Tonga exploded, releasing large amounts of energy into the atmosphere and ocean, causing tsunamis across the Pacific Ocean. Scientists from the Shocks, Solitons ...

Researchers develop a model to better understand the forces that generate tsunamis

The word "tsunami" brings immediately to mind the havoc that can be wrought by these uniquely powerful waves. The tsunamis we hear about most often are caused by undersea earthquakes, and the waves they generate can travel ...

A 127-year-old physics riddle solved

He solved a 127-year-old physics problem on paper and proved that off-centered boat wakes could exist. Five years later, practical experiments proved him right.

Floating ocean plastic can get a boost to its wave-induced transport because of its size

Plastic pollution and other ocean debris are a complex global environmental problem. Every year, ten million tons of plastic are estimated to be mismanaged, resulting in entry into the ocean, of which half will float initially. ...

Turbulence meets a shock

This may come as a shock, if you're moving fast enough. The shock being shock waves. A balloon's 'pop' is shock waves generated by exploded bits of the balloon moving faster than the speed of sound. Supersonic planes generate ...
