内容記述 | 一様流中に置かれた角柱列を過ぎる流れの安定性を数値的に解析した。2次元非圧縮性流れ場を仮定した。列のピッチ対直径比が大きい場合、角柱の間隙を通るジェットは互いに独立であることを見出した。しかし、ピッチ対直径比が小さい場合、数個のジェットの合流が起こる。2つまたは3つのジェットの合流はピッチフォーク分岐によること、およびピッチフォーク分岐に対する臨界レイノルズ数はピッチ対直径比のそれぞれの値に対して評価されることが分かった。流れ場の可視化実験も行い、ジェット合流を確かめた。 | |||||

内容記述 | The stability of the flow past a row of square bars, which is placed across a uniform flow, is investigated numerically. Two-dimensional and incompressible flow field is assumed. It is found that each jet which flows between the square bars is independent of each other when the pitch-to-diameter ratio of the row is large. However the confluence of several jets occurs when the pitch-to-diameter ratio is small. It is found that the confluence of couples or triplets of jets is a consequence of a pitchfork bifurcation and the critical Reynolds numbers for the pitchfork bifurcations are evaluated for each value of the pitch-to-diameter ratio. An experiment to visualize the flow field is also made and the confluence of jets is confirmed. | |||||
