“…The next test is how the characteristics of a single rotor wind turbine at lower freestream wind speed conditions by maintaining the same TSR value of the turbine operation (Make & Vaz, 2015). Decreasing the inflow velocity (freestream) with the same TSR which directly decreases the Reynolds or Re number scale (Burmester et al, 2016) as in Eq. 5.…”

Numerical analysis was conducted on the aerodynamic performance and the flow characteristics around the counter-rotating wind turbine or CRWT blade through rear rotor configuration using various rotor diameter ratios and distance ratios to the turbine blade through a CFD (Computational Fluid Dynamics) simulation. CFD simulation showed the normalized power coefficients of the front rotor, rear rotor, and combined rotor (CRWT) to the single rotor with a strong influence of the rear rotor configuration with the addition of tip speed ratio (TSR). A larger average normalized power coefficient takes place at D1/D2=1.0 with L/D1=0.75 by 1.221. It is about 22.1% increased to the SRWT for the given TSR range. Axial velocity contours and resultant velocity vectors around the CRWT blade with a diameter ratio of D1/D2 > 1.0 and a closer rotor distance provide a stronger bound vortex and strong separation around the rear hub blade with a tendency to increase from the hub to the tip blade at low TSR. The higher the TSR, the movement of tip vortex moves closer to the rear tip blade which has the effect of increasing the leakage flow in the area of D1/D2 < 1.0.

“…Emplean el programa GH Bladed 4.5 para simular dos turbinas de capacidades de 2 MW y 5 MW, con el fin de comparar su respuesta. Los autores Burmester et al [1] comparan los coeficientes de sustentación y de arrastre de un prototipo de aerogenerador, obtenidos mediante simulación, con los datos obtenidos durante el funcionamiento de un aerogenerador real. Khan [8] realiza el modelado, simulación y análisis de una pequeña turbina aislada, mediante conjuntos de relaciones empíricas y físicas, además de su simulación digital.…”

En este trabajo se diseña e implementa una metodología para escalar el modelo de una turbina eólica de potencia nominal determinada al de una turbina de diferente potencia. Para ello, se presentan e implementan en MATLAB/Simulink los modelos que describen el funcionamiento de un aerogenerador, se identifican los parámetros que definen su potencia nominal, y se enumeran y aplican las modificaciones que deben realizarse para escalar un modelo a otro. Los resultados de simulación confirman la viabilidad de esta metodología, que puede resultar muy útil para obtener de forma sistemática y más sencilla el modelo de las más complejas turbinas de gran tamaño.
