Ordering of small particles in one-dimensional coherent structures by time-periodic flows
time-periodic flows small particles Ordering one-dimensional coherent structures
2011/7/7
Small particles transported by a fluid medium do not necessarily have to follow the flow. We show that for a wide class of time-periodic incompressible flows inertial particles have a tendency to spon...

We consider the one-dimensional propagation of electromagnetic waves in a weakly nonlinear
and low-contrast spatially inhomogeneous medium with no energy dissipation. We focus on the case of a period...
基于小波和双谱分析的湍流相干结构辨识（Identification of Turbulent Coherent Structures Based on Wavelet and Bi-spectrum Analysis）
湍流信号 相干结构 双谱
2009/11/24
为了从湍流信号中获取更多关于相干结构的定量信息，提出了一种基于小波和双谱分析的辨识相干结构的方法。该方法通过双谱和互相关分析合理地得到了包含相干结构信息的大涡信号，利用小波变换有效地提取出表征湍流多尺度相干结构的信号成份。建立了基于小波分析辨识湍流含能尺度的能量最大准则，以沟槽壁面减阻机理实验的湍流数据分析为例，验证了该方法的合理性和可靠性。
