| 摘 要： | 采用粒子图像测速仪对矩形槽道内表面活性减阻流体在流动方向(x方向)与壁
面垂直方向(y方向)所在平面的流场进行了测量，分析了速度、涡量、速度脉
动相关量在流场内的瞬态分布，以及对500幅相同工况的流场进行了统计平均. 结
果显示: 与牛顿流体相比, 表面活性剂减阻流体接近于层流流动，横向速度脉动被大幅
减弱，导致湍流输运减弱，雷诺应力远远小于水. 减阻流体流向速度脉动呈条带
特征，沿流动方向发展，反映了减阻流体不同于水的湍流输运特征.

| Abstract: | In the dilute surfactant drag-reducing flow,the slight viscoelasticity of solution affects the energy dissipation process of the flow,and this flow exhibits special fashion different from laminar flow or turbulent one in Newtonian fluid.The study on the modification of turbulent structures by the viscoelasticity of the solution is important to clarify the drag reduction mechanism of surfactant solution flow.In this paper,drag reducing flow of dilute surfactant solution in the two dimensional rectangle chann... |
