Similarly, if is negative the traveling wave solution propagates towards the left, the left side is called downwind side and right side is the upwind side. If the finite difference scheme for the spatial derivative, ∂ u / ∂ x {\displaystyle \partial u/\partial x} contains more points in the upwind side, the scheme is called an upwind-biased ...
A diagram of a panemone whose wind-catching panels are arranged to turn edge-on to the wind when moving against the wind's thrust, and side-on when moving downwind to harness the wind's motion. A panemone windmill is a type of vertical-axis wind turbine. It has a rotating axis positioned vertically, while the wind-catching blades move parallel ...
English: A turbine and gear box are mounted in a casing called a nacelle, and rotor blades are attached to the turbine. The turbine localizes the energy of the turning rotor blades in a single rotating shaft that generates electricity.
An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
The French wind turbine manufacturer Vergnet has several medium and large self-orienting downwind wind turbines in production. Passive yaw systems have to be designed in a way that the nacelle does not follow the sudden changes in wind direction with too fast a yaw movement, in order to avoid high gyroscopic loads.
Windward is upwind from the point of reference, i.e., towards the direction from which the wind is coming; leeward is downwind from the point of reference, i.e., along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side".
Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.
