Slow Mo Pulse Jet Engine

Nicole Sharp - January 11, 2021December 18, 2020

Pulse jet engines rely on their shape to maintain combustion without moving parts. The pressure waves that travel through the engine pump fresh oxygen into the combustion chamber and then Keep reading

Jets Beneath Leidenfrost Drops

Nicole Sharp - December 7, 2020November 18, 2020

When a droplet impacts, it’s not unusual for converging ripples to form an upward jet, like the one seen here. But under the right circumstances, jets can form downward, too. Keep reading

Droplets From Jets

Nicole Sharp - August 17, 2020July 27, 2020

On the ocean, countless crashing waves are creating bubbles. When they burst, those bubbles generate jets and droplets that spray into the sky, carrying sea salt, dust, and biological material Keep reading

Surface Jets in Coalescing Droplets

Nicole Sharp - February 26, 2020February 25, 2020

What goes on when droplets merge is tough to observe, even with a high-speed camera. There are many factors at play: any momentum in the droplets, surface tension, gravity, and Keep reading

Swinging Jets

Nicole Sharp - January 14, 2020January 13, 2020

In the tiny realm of microfluidics, flows are, in general, completely laminar. That makes mixing a challenge. But it turns out that pumping water steadily into multiple inlets can spontaneously Keep reading

Feathered Fighter Jets

Nicole Sharp - August 22, 2019October 30, 2019

Peregrine falcons are built for speed. They’ve been clocked at more than 380 kilometers per hour when diving. This video from Deep Look examines some of the features that make these birds of Keep reading

Jets from Lasers

Nicole Sharp - July 25, 2019November 6, 2019

Laser-induced forward transfer (LIFT) is an industrial printing technique where a laser pulse aimed at a thin layer of ink creates a tiny jet that deposits the ink on a surface. In Keep reading

Plant Week: Citrus Jets

Nicole Sharp - May 16, 2019October 29, 2019

Bartenders and citrus lovers the world over are familiar with the mist of oil that bursts from a bent citrus peel. These microjets are about the width of a human Keep reading

Noisy Jets

Nicole Sharp - March 1, 2019October 28, 2019

One major problem that has plagued supersonic aircraft is their noise. The Concorde – thus far the only supersonic commercial airliner – was plagued with noise complaints that ultimately restricted Keep reading

Massive Worthington Jet

Nicole Sharp - February 15, 2019November 5, 2019

The FloWave facility in Scotland is one of the coolest ocean simulators out there. Equipped with 168 individual wave makers and 28 submerged flow-drive units, it’s capable of recreating almost Keep reading
