A 3 - d wave model for the coherent structures 1mm in the outer region of a turbulent 1mm boundary layer 湍流边界层外区相干结构的三维波模型
2.
Artificial periodic disturbances are introduced to the outer field of turbulent boundary layer in an closed - circuit open water channel . statistical method is employed for analyzing the velocity - fluctuation - time - series . the effect of the disturbance to turbulent structure in boundary layer is studied 在开口式循环水槽底部湍流边界层外区中引入周期性扰动,对湍流场的速度脉动时间序列信号进行了统计分析,研究了湍流边界层中周期性人工扰动对湍流结构的影响,结果表明高频扰动的湍流中she - leveque简称sl湍流层次相似律成立。
