【摘要】 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。更多还原

【Abstract】 In this paper, the experimental data of the multi channel scanning probe for the experiment of the hypersonic plasma flows in the arc-heated tunnel are analysed by using method of the chaotic dynamics. It is given that the distributions of correlation dimension and Kolmogorov entropy of the blunted cone wake flows and no blunted cone flows, which successfuly capture the turbulence and demarcation layer structure in the flows. The bow shock structure of blunted cone wake flow is observed by the method of Kolmogorov entropy minimum values.更多还原
