Researchers at the Weizmann Institute of Science, the University of Rome, CNRS and the University of Helsinki have recently carried out a study investigating the difference between 3-D anisotropic turbulence in classical ...
How much stress do pipes undergo when a liquid flows through them, and how does it depend on the degree of curvature of the pipe?
Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating ...
Turbulence plays a key role in our daily lives, making for bumpy plane rides, affecting weather and climate, limiting the fuel efficiency of the cars we drive, and impacting clean energy technologies. Yet, scientists and ...

When long-chain flexible polymers are dissolved in a turbulent flow, the flow properties can be changed drastically by reducing the drag and enhancing the mixing. A fundamental riddle in materials science is to understand ...
New research from North Carolina State University shows that unique materials with distinct properties akin to those of gecko feet—the ability to stick to just about any surface—can be created by harnessing liquid-driven ...

For the kinds of animals that are most familiar to us—ones that are big enough to see—it's a no-brainer: Is it better to sit around and wait for food to come to you, or to move around and find it? Larger animals that ...
