Abstract Modern wind turbines employ thick airfoils in the outer region of the blade with strong adverse pressure gradients and high sensitivity to flow separation, which can be anticipated by leading‐edge roughness. However, Reynolds average Navie

Flow separation is the source of several problems in a wind turbine including load fluctuations, lift losses, and vibrations. Vortex generators (VGs) are passive flow control devices used to delay flow separation, but their implementation may produce

Vortex generators (VGs) are increasingly used in the wind turbine manufacture industry as flow control devices to improve rotor blade aerodynamic performance. Nevertheless, VGs may produce excess residual drag in some applications. The so-called sub-

This work features a method to obtain the spatially resolved distribution of the local ideality factor, n loc , based on variations in terms of the saturation of the recombination current from the difference of injected currents between neighboring p

Treatment adherence measurement can be time and resource-intensive in clinical trials, so the ability to measure protocol adherence for two distinct treatment programs with a single measure may benefit the field. The present study sought to determine

Laser processes in solar cells are the origin of a considerable mechanical and electrical damage. This paper introduces a model that presents a good fitting to the laser-induced damage, previously characterized as an extra recombination diode, with a

An Ecuadorian lease ("Bloque 61") composed of 14 oil fields represents the most productive asset in the country. It contains 5.3 billion barrels of original oil in place (OOIP) distributed in four complex producing reservoirs. After 44 years of produ

El problema de los tres cuerpos sometidos a la ley de Gravitacion universal se ha trabajado desde el siglo XVII y esta lejos de ser resuelto. Se han encon- trado soluciones particulares y algunas aproximaciones numericas conables a otras soluciones.

The local ideality factor analyses the localized evolution of the ideality factor with relation to the voltage. In this paper a single diode model is used, by means of its asymptotic behavior, to outline the role of the characteristic parameters of t
