1) blowing and suction
吹吸扰动
1.
Effect of blowing and suction on friction drag of wall turbulent boundary layer
吹吸扰动对壁湍流边界层摩擦阻力的影响
2.
The streamwise velocity component in the wall turbulent boundary layer disturbed by blowing and suction was measured with hot wire anemometer.
采用热线风速仪测量受吹吸扰动的壁湍流边界层的流向速度,用傅里叶变换和子波变换研究吹吸扰动对壁湍流能谱的影响,结果显示施加的低频扰动使边界层内层大尺度结构的能量减少,小尺度结构的能量有所增强,远离壁面时扰动强度逐步衰减直到在外层中消失；通过VITA法和子波变换法检测猝发事件,表明该扰动降低了猝发强度,使猝发周期延长,条件平均速度波形的幅值降低、持续时间变短,说明扰动明显抑制了相干结构的猝发过程,利用子波变换可以实现湍谱分析,能有效检测猝发中的湍流结构,是一种客观的分析工具。
