The view from inside supersonic combustion

In a jet engine, the flow of air is slowed down to increase the temperature and pressure for combustion—burning fuel with the right ratio of fuel and air to conquer drag allows for acceleration.

Controlling a vortex using polymers

A vortex in the atmosphere can churn with enough power to create a typhoon. But more subtle vortices form constantly in nature. Many of them are too small to be seen with the naked eye.

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 ...

New bubbling mechanism discovered in physics

A group of researchers at Zhejiang University's State Key Laboratory of Fluid Power and Mechatronic Systems, in Hangzhou, China, recently discovered that a new bubbling mechanism may exist within the realm of physics.

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.

Underwater vehicle design inspired by schools of fish

It is easy to speculate why fish might swim in schools—better protection from predators, improved foraging capability, easier fish-to-fish communication. Yet, none of these reveal why fish might move together in a specific ...

Experts investigate how order emerges from chaos

Igor Kolokolov and Vladimir Lebedev, scientific experts from HSE's Faculty of Physics and the Landau Institute for Theoretical Physics of Russian Academy of Sciences, have developed an analytical theory binding the structure ...

Blocks of ice demonstrate levitated and directed motion

Resembling the Leidenfrost effect seen in rapidly boiling water droplets, a disk of ice becomes highly mobile due to a levitating layer of water between it and the smooth surface on which it rests and melts. The otherwise ...
