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 ...

Turbulent flows in pipes are of importance for many every-day applications. What they all have in common is their appearance: They travel down the pipe bubbling and gurgling like a mountain stream.

In this talk we will consider two canonical flow cases, Couette and ASBL (asymptotic suction boundary layer) flow, and study two aspects related to transition to turbulence. In Couette flow (and other ...

Whether in oil pipelines or city water mains -- scientists have discovered that turbulent flow is not stable. When a flow reaches a certain speed, things get turbulent: The fluid or the gas no longer ...
