円柱まわりの流れに円柱軸方向の音響的かく乱を加えた場合について,円柱からのうず発生と音響との干渉,特にスパン方向の流れの変化を実験的に調べ,次の結論を得た.すなわち,円柱軸方向の音響的かく乱は軸に直角方向のかく乱と同様の効果を与え,うず糸の二次元性を改善する.また,うず発生に影響を及ぼす音波の周波数はせん断層内の遷移波の周波数に関係したものであり,その音波の強さには臨海値が存在することを確かめた.

翼列における二次流れの下流方向への変化過程を解明するため,減速の直線翼列について実験的研究を行った.翼列出口で渦面をなす随伴渦は最大強さの位置から巻き始め,2弦長下流ではほぼ軸対称な渦となる.その減衰は流路渦に比べて翼列出口で急速で,巻上がりに伴い純る.随伴渦は非粘性古典理論の予測に比較して,また流路渦と比べても側壁からかなり遠くに生じ,ピッチ平均の二次渦度および転向角の減少に大きく寄与する.

An analysis is given for determining the unsteady pressure on a cambered blade with angle of attack moving through both longitudinal and transverse gusts. The nondimensional unsteady pressure functions are defined for seven combinations of the effects of longitudinal and transverse gusts, angle of attack and camber. Based on these functions, examples of obtained results describing the unsteady pressure distribution on the blade are presented.
