内容記述 | R(sub λ)=80〜393の乱流場の統計的性質を実験的に調べた。乱流強度、エネルギースペクトル、および速度変動のPDF(確率密度分布)を求め、非等方テンソルスペクトルを導いた。乱流エネルギーと非等方テンソルの不変量Πとの関係は、等方化過程が、乱流の自己相似性に達する下流域で、減衰過程へと移行することを示した。l(sub D)を最大散逸渦スケール、l(sub G)を最大等方乱流渦スケールとしたとき、l(sub D)〜l(sub G)で定義した慣性小領域は、R(sub λ)=393について、1桁以上の波数領域をカバーした。減衰率および無限大極限のR(sub λ)でのKolmogorov定数についても推算した。 | |||||
