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 ...

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 ...

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 ...

The effectiveness of the mixing process can be key to determining whether the overall process is viable on any scale and can be the difference between a reaction working and the difference between a ...

A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

If one looks at many practical fluid flows, either around bodies (flow of air over an airplane wing) or through conduits, (flow through pipes), the problem of turbulence presents itself in almost ...

Using unconventional statistical mechanics to understand fluid dynamics, a professor helped solve a 150 year old physics problem of how turbulent fluids move through a pipe. In 1883 Osborne Reynolds ...

The boundary layer, a tiny layer on the surface of a body in a flowing fluid, such as an airplane wing in the air, is of paramount importance for the future of flight. Just over 100 years ago, Ludwig ...

This release is available in German. When a flow reaches a certain speed, things get turbulent: The fluid or the gas no longer flows in an orderly fashion but whirls around wildly. However, in ...
