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 ...

Turbulence is one of the great mysteries of modern science. It is also one of the most important, as most of the flows we’re interested in are turbulent. In some applications, such as industrial ...

Turbulence, the chaotic, irregular motion that causes the bumpiness we sometimes experience on an airplane, has intrigued scientists for centuries. At the Okinawa Institute of Science and Technology ...

Introduction Have you ever seen a wind turbine? Wind turbines are large towers with blades on top that are spun by the wind. They are one source of clean, renewable energy. They use the movement from ...

One of the first things most people do in the morning is turn on a tap in the bathroom. Provided we are not too sleepy, we cannot fail to notice what is often considered to be the greatest unsolved ...

Making science for people is a series that explores how humanities, arts and social sciences expertise is applied to problems typically corralled into the science and technology space. The first piece ...

The flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterised by chaotic motion and large amounts of mixing. In this ...

People complain about fan noise in their computers. The same applies to active cooling on high-power LED arrays. It's not CFM (cubic feet per minute) that counts, but the linear air velocity at the ...

Patients with pulsatile tinnitus are beset by a sound that surges with every beat of their heart. For those who seek medical ...
