 note = {熱線風速計を用いて主流に直角に置かれた円柱の後端における速度変動を調べた。後流中に見出されるスパイクと呼ばれる間欠的な大きくて鋭い速度変動は、出現の持続性からr.m.s.(自乗平均平方根)値への寄与が大きい定常的な振幅の小さい変動に比べて横方向には遥かに広く分布する傾向をもつ。そのようなスパイクは、円柱から比較的遠くへ離して置いた平板の上の乱流遷移に支配的な役割を果すことが見出された。本報告では、円柱の後流におけるスパイクの拡がりの概略を示した。, Velocity fluctuations were investigated with hot-wire anemometers in the wake of a circular cylinder placed perpendicular to the main stream. Large and sharp fluctuation of velocity though occasional, designated 'spike', found in the wake, tends to distribute itself transversely much wider than steady small fluctuations which contribute most to the r.m.s. (root-mean-square) value because of persistent appearance. With the cylinder set rather far from a plate (parallel to the flow), for its boundary layer transition to turbulence, such spikes are found to play the dominant role. In this paper, an outline of extent of the spike in the wake of the cylinder is presented., 資料番号: AA0004172019, レポート番号: NAL SP-25},
