 note = {後向きステップまたは長方形の溝による流れの剥離について, 壁面に沿う圧力分布ならびにいくつかの横断面での平均および変動速度の分布を低速風路で測定した。ステップの圧力分布は, ステップの高さまたはステップ上流の境界層の厚さの変化によって, あまり大きな影響を受けることがない。これはステップの後に生ずるくぼみ流れ(腔流)の平衡が保たれ, それにはたらく壁面の圧力と, ステップの高さおよびステップ上流の境界層にほぼ無関係に混合領域に発生する乱流剪断応力が釣合うことを考えると理解できる。溝を越える流れは, 溝が深いか浅いかによって著しく異なるが, その境目は溝の深さと幅の比がおよそ0.7の附近にある。深い溝の場合には, 流れは比較的に滑かで, 圧力抵抗は小さい。浅い溝では反対である。溝の中のくぼみ流れは, ステップの場合と同じようにその平衡が保たれる。, Low-speed measurements were made on the flow separation associated with a backward-facing step or a rectangular groove by determining the distribution of pressure along the surface and the distributions of mean and fluctuating velocities across several transverse sections. The pressure distribution was found to be rather insensitive to the changes in step height and thickness of the approaching boundary layer. This can be understood by realizing that the cavity flow behind the step is maintained in equilibrium such that the pressure exerted by the solid surface is balanced by the turbulent shear stress, which is set up in the mixing region approximately independently of the step height and the approaching boundary layer. The flow over a groove is markedly different according as it is deep or shallow, the demarcating value of depth-breadth ratio beind around 0.7. The deep-groove type of flow is characterized by a comparatively smooth flow and a low value of pressure drag. The converse is true of the shallow grooves. The cavity flow region inside the groove is maintained in equilibrium similarly as in the case of flow over a step., 資料番号: SA2404866000},
