Abstract

lâmina para uma ventoinha de uma turbomáquina, principalmente do tipo ventoinha não carenada, ventoinha correspondente, e turbomáquina correspondente. lâmina para uma ventoinha de uma turbomáquina, principalmente do tipo ventoinha não carenada, ventoinha correspondente e turbomáquina correspondente. de acordo com a invenção, a lâmina (11a) compreende meios (16) arranjados em uma única localização, de modo que eles, de maneira localizada, quando a ventoinha (7) gira, perturbem a distribuição de fluxo ao redor da lâmina (11a) de modo a formar dois vórtices principais independentes a jusante.
