When the layers in the shear flow become wrinkled the motion grows complicated, especially when the wrinkles roll up into whirls.
當剪流中流體層開始起皺,尤其是皺褶捲曲成旋渦時,運動就復雜化了。The results are compared with the cases in a single - layer fluid, showing that the density stratification can have a relative large effect on the drag and lift coefficients as well as the vortex shedding
計算受迫振蕩圓柱體的升力系數、阻力系數隨時間的演化曲線和圓柱體的尾渦分佈,以及圓柱體的受迫振蕩激發兩層流體內界面的擾動,並與均勻流體的情況進行了比較分析。Navier - strokes equation was solved using simple method. lam - bremhorst k - e was used to simulate turbulent flow. it was indicated in this thesis that a longitudinal vortex would be produced after the jet exhausted from a plate into a boundary layer at a pitch angle and a skew angle
研究結果表明,有一定傾斜角度的單個射流與主流作用后,將在下游產生一個流向渦旋,渦旋使得邊界層內的速度和雷諾應力發生嚴重扭曲,從而形成上洗區域和下洗區域。Curved vortex sheet
