Solar wind turbulence displays both magnetohydrodynamic (MHD) and kinetic plasma behaviors. It exhibits Kolmogorov-like power spectra at fluid scales, and shows strong Alfvénic correlations between velocity and magnetic field fluctuations, especially in fast solar wind. It evolves with distance from the Sun as the wind expands.
Software helps design wind turbines. There are several aero-elastic packages that are used in this design process. FOCUS6 aids in the design of wind turbines and turbine components such as rotor blades. It was developed by Knowledge Centre Wind turbine Materials and Constructions (WMC) [1] and Energy Research Centre of the Netherlands (ECN). [2]
The solar wind is observed to exist in two fundamental states, termed the slow solar wind and the fast solar wind, though their differences extend well beyond their speeds. In near-Earth space, the slow solar wind is observed to have a velocity of 300–500 km/s , a temperature of ~ 100 kilokelvin and a composition that is a close match to the ...
Furthermore, a Free Wake Vortex model was implemented for the accurate representation of the near and far wake of the turbine. A new version of QBlade was released in August 2022. QBlade Community Edition (QBlade-CE 2.0.4) includes all functionality that is required for the aero-servo-hydro-elastic simulation of wind turbines.
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
Vortex Bladeless Ltd. is a Spanish technology startup company that is developing a specific type of wind power generator without rotating blades or lubricants. [1] Power is produced from resonant vibrations when wind passes through the turbine and is deflected into vortices in a process called vortex shedding.

The power coefficient [9] C P (= P/P wind) is the dimensionless ratio of the extractable power P to the kinetic power P wind available in the undistributed stream. [ citation needed ] It has a maximum value C P max = 16/27 = 0.593 (or 59.3%; however, coefficients of performance are usually expressed as a decimal, not a percentage).
