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 ...

Nature does not allow us to increase the size of a system without eventually losing coherence. For example, although a coherent laminar flow through a pipe is always linearly stable, increasing the ...

The flagship demonstration under Europe’s Clean Sky civil aeronautics research program is entering the hardware stage, aiming for first flight of the Airbus A340-300-based laminar flow wing ...

Painstaking assembly of ultrasmooth wing sections for Europe’s Airbus A340-based natural laminar flow demonstrator is set to start as the first structural components begin arriving at Aernnova in ...

Fluid dynamics is "the branch of applied science that is concerned with the movement of liquids and gases," according to the American Heritage Dictionary. Fluid dynamics is one of two branches of ...

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 ...

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 ...
