Validation of the noise prediction code Rnoise and reduction of trailing edge noise by Active Flow Control

Vengono esposte le principali fonti di rumore di una turbina eolica, e i problemi ad esse legate. Utilizzando un algoritmo di previsione del rumore originato dalla trailing-edge, basato su risultati di simulazioni RANS 2d, le previsioni vengono confrontate con risultati sperimentali disponibili. Vengono inoltre ricercate le condizioni ottimali per un attuatore posto sull'estradosso del profilo che aspiri lo strato limite con l'obiettivo di ridurre le emissioni sonore stimate
