| Abstract: | Trata-se de urna análise do desempenho de rotores eólicos Darrieus com pás retilíneas e pás troposkianas e comparação entre os perfis simétricos NACA 0012 e NACA 0015. O trabalho consistiu na construção de um freio dinamormétrico de Prony e de modelos em escala reduzida (altura= diâmetro = 5OO mm) que foram testados em um túnel de vento com área da seção de testes igual a 1 rn 2 e velocidade máxima de vento em torno de 8,0 rn/s. Os resultados experimentais foram comparados com aqules dos modelos teóricos. |
| Abstract: | Performance analyse of a Darrieus rotor with straight an.d troposkien blades using NACA 0012 and NACA 0015 profiles was realized. A reduzed scale model (height = diameter = 500 mm) with "Prony" brake dynamometer was tested in a wind tunnel with a 1 m2 test section and maximum wind velocity of 8,0 m/s. The experimental results were compared with those of the theoretical computer model. |
