A link between the turbulent cascade and the dynamics of transition

利用在边界层转捩中逐渐建立起来的主要动力学过程 ,对湍流级串概念做了进一步的分析 .对边界层转捩的测量结果进行定量分析 ,从所得能谱中可以清楚看到湍流级串与转捩的动力学过程的对应关系 ,进而丰富了对湍流级串的理解The transitional primary dynamical processes, which were constructed in the experiment in a transitional boundary layer, were used to make further analysis on the turbulent cascade patterns. The quantitative results obtained from the measurement data in the transitional boundary layer experiment described the link between the turbulent cascade patterns and a sequence of transitional primary dynamics processes. This may be helpful for us to understand the turbulent cascade more deeply.SCI(E)中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)0082621-26245
