In order to study the convection velocity of multi-scale eddy structures in turbulent flow field with the background of high turbulent intensity and wide range of eddy scales, velocity measurements are carried out at different places on the center line of turbulent jet flow with circular nozzle with IFA300 double-channel anemometer and two hot-wire probes.
在流场背景湍流度比较大或流场中涡结构的尺度范围比较宽的情况下,为了研究湍流场中不同尺度涡结构的迁移速度,用IFA300双通道恒温热线风速计和两个热线探针测量圆自由射流中心线上距离一定的空间两点同一时刻的流向速度分量,用子波分析提取了每一个探针输出的不同尺度的脉动速度信号,计算了两个探针输出的同一尺度脉动速度信号的互相关函数,利用互相关函数达到最大值对应的延迟时间研究了湍流多尺度涡结构的迁移特性。

The convection velocity in the turbulent boundary layer plans an important role in describing the characteristics of transportation of the momentum, quality and energy in turbulence, serving as a bridge between spatial description and temporal description in the studying of turbulence, and Taylor’s frozen hypothesis that we often used is also related to the convection velocities for turbulence.
湍流边界层中多尺度湍流结构的对流迁移速度对于研究湍流中动量、质量和能量的传递和输运过程有着重要的意义,充当着湍流研究中时间描述与空间描述的桥梁,并且在湍流研究中经常引用的泰勒冻结假设也涉及到湍流结构的迁移速度,但是,如何确定不同尺度湍流结构的迁移速度至今尚未有明确的方法。
