内容記述タイプ | Abstract | |||||
内容記述 | 従来からある2つの手法、すなわち観察と計測を渦流れの場合に適用し、この2つの手法の関係を論じた。これらの手法は、渦パターンの観察が瞬間的な流れの空間的変化を知るのに有用である一方、速度変動の計測が空間の1点における流れの時間的変化を知るのに有用であることから、非定常の渦流れを十分に理解しようとするときに互に相補うものである。渦流れの空間変化と時間変化の双方を知るために、速度場を水素気泡法で計測する新しい方法を開発した。この方法を用いてカルマン渦列における速度場を計測し、円柱の近傍における断面流線図と渦度の等高線図を定めた。 | |||||

内容記述 | Two conventional methods, i.e., observation and measurement, have been applied to investigate the vortex flows. The relation between the observation and the measurement are discussed. Two methods are complementary to each other in a full understanding of the unsteady vortex flows, since the observation of vortex patterns is useful to know the spatial variation of the flow at an instant and the measurement of velocity fluctuation is useful to know the temporal variation of the flow at a local point. In order to know both spatial and temporal variation of vortex flows, a new method was developed to measure the velocity field by means of hydrogen bubble techniques. By use of the method the velocity field in Karman vortex streets were obtained and the patterns of sectional streamlines and contours of vorticity were determined in the region of the near of a cylinder. | |||||
