Abstract

taxas de turbina eólica savonius. uma turbina eólica savonius foi observada no passado por ter a capacidade de funcionar de forma mais eficiente do que outras turbinas de eixo vertical do tipo arrasto quando construída de acordo com certos parâmetros. a literatura anterior deixou de ver a relação entre o diâmetro do eixo e o espaço disponível para a passagem do vento no centro como a relação crucial na qual outras melhorias neste tipo de turbina podem ser construídas. o diâmetro da corda e a distância de sobreposição dependem do tamanho do eixo central e sua relação com os pontos finais internos das lâminas semicirculares sobrepostas. as taxas para eficiência máxima são apresentadas aqui. essas taxas eficientes também dependem para sua execução na turbina girando em uma relação de velocidade de ponta ideal.
