Based on self-developed image-based laser measurement system for instantaneous concentration field, overcoming the difficulties of measuring instantaneous concentration fields, the unsteady two-phase flow around a cylinder is investigated to obtain the concentration time series.
克服瞬时浓度场测量的困难,利用自行研制的瞬时浓度场激光图像测量系统,对绕圆柱不稳定两相流动进行实验测量,获得了浓度场时间序列,并发展了一种浓度场信息熵计算方法,得到了浓度场信息熵时间序列,最后对这些时间序列进行了关联维数(系统复杂度的估计)、Kolmogorov熵(动力系统的混沌水平)和Lyapunov指数(系统稳定性的特征指数)等非线性分析。
