摘要
本文主要讨论了光滑壁边界层相干结构的特性，建立了这种相干结构的物理模型，从理论上得到慢条宽度、猝发时间等物理量与动量厚度雷诺数的关系，其结果与实验结果￣［３’４’５’７］是相吻台的。
In this paper,based on the discussion of properties of the turbulent coherent structure for smooth boundary layer,a physical model has been established.The width of slowly-moving streak line and bursting time of coherent structure exp-ressed by momentum thickness Reynolds number of boundary layer have been obtained, which are in agreement with the experimental data￣ [3,4,5,7]
