B}, month = {Jun}, note = {We have experimentally studied the relationship between the periodic velocity fluctuation in the near wake of a rotating NACA 65 Blade and the generated broad band noise at different setting angles of the blade. The typical periodic velocity fluctuation in the near wake was not clearly observed at a design point but was observed at the attack angle at off design points. The frequency of the produced velocity fluctuation caused by Karman vortex shedding from the trailing edge of the blade increased toward the tip of the blade. Then, the spectrum of noise generated from the blade becomes broad band. In addition, we have proposed a method to predict the spectrum of noisc generated from blades due to Karman vortex shedding. The validity of the method was experimentally verified.}, pages = {2047--2054}, title = {回転する単独NACA65翼から発生する騒音のスペクトル密度分布の予測}, volume = {63}, year = {1997}, yomi = {フカノ, トオル and サルワタリ, ヒロタカ and キタムラ, トモオ and ハマカワ, ヒロミツ} }
