How fluids flow through shale

Most of the world's oil and natural gas reserves may be locked up inside the tiny pores comprising shale rock. But current drilling and fracturing methods can't extract this fuel very well, recovering only an estimated 5 ...

Nature plants a seed of engineering inspiration

Researchers in South Korea have quantitatively deconstructed what they describe as the "ingenious mobility strategies" of seeds that self-burrow rotationally into soil. This is an example of the many ways nature uses biological ...

Lasers measure jet disintegration

There are many processes, such as propulsion, in which fluid in a supercritical state, where the temperature and pressure put a substance beyond a distinguishable liquid or gas phase, is injected in an environment of supercritical ...

Inventing a new kind of matter

Imagine a liquid that could move on its own. No need for human effort or the pull of gravity. You could put it in a container flat on a table, not touch it in any way, and it would still flow.

How water flows near the superhydrophobic surface

Water has an unusual property when it flows closely to some specially designed surfaces—its speed isn't equal to zero, even in the layer that directly touches the wall. This means that liquid doesn't adhere to the surface, ...

Measuring the flowing forces and bending on aquatic plants

Beneath the surface of rivers and streams, aquatic plants sway with the current, playing an unseen but vital role in the life of the waterway. Through a new series of experiments that model these underwater undulations, researchers ...

Engineers stop soap bubbles from swirling

The spinning rainbow surface of a soap bubble is more than mesmerizing – it's a lesson in fluid mechanics. Better understanding of these hypnotic flows could bring improvements in many areas, from longer lasting beer foam ...

Quest to find the 'missing physics' at play in landslides

During the 1990s, Charles S. Campbell, now a professor in the Department of Aerospace and Mechanical Engineering at the University of Southern California, began exploring why large landslides flow great distances with apparently ...

Researcher investigates the forces behind complex fluids

Sunscreen, laundry detergent, the can of paint you just picked up from the hardware store. What if we told you that your everyday liquid consumer products aren't just liquids—they're a complex blend of liquid and solid ...

Innovative approach makes for a smoother ride

Moving through water can be a drag, but the use of supercavitation bubbles can reduce that drag and increase the speed of underwater vehicles. Sometimes these bubbles produce a bumpy ride, but now a team of engineers from ...

How much can a mode-2 wave move?

Look out over the ocean and you might get the impression that it's a mass of water acting as a single entity. However, the world's oceans are made up of layers of different densities, called stratifications, with complex ...

Daffodils help inspire design of stable structures

In 1940, the Tacoma Narrows Bridge collapsed in dramatic fashion, twisting in the wind before it snapped and plunged into the water below. As wind blew across the span, the flow induced oscillating sideways forces that helped ...

Enhancing lab-on-a-chip peristalsis with electro-osmosis

If you've ever eaten food while upside down - and who hasn't indulged this chimpanzee daydream? - you can thank the successive wave-like motions of peristalsis for keeping the chewed bolus down and ferrying it into your stomach. ...
