本文采用耗散系统的混沌动力学方法，分析处理了ＦＤ０４ 电弧风洞超高速等离子体流场实验中多道扫描探针的实验数据。分别给出了无锥体流场和有锥体尾迹等离子体流场的相关维数和Ｋｏｌｍ ｏｇｏｒｏｖ 熵值的分布。该分布清晰地刻划了流场的湍动和分层结构。用Ｋｏｌｍ ｏｇｏｒｏｖ 熵极小值方法，观测到了锥体尾迹流场的主激波结构。
In this paper, the chaotic dynamics of dissipative system is used to analyze and deal with the experimental data of multi-channel scanning probe in the field experiment of ultra-high-speed plasma in FD04 arc wind tunnel. The correlation dimension of Kolmogorov entropy and the distribution of Kolmogorov entropy are given respectively. The distribution clearly characterizes the turbulence and the stratification of the flow field. The Kolmogorov entropy minimum method was used to observe the main shock structure of the cone wake flow field.
