中文摘要：

高焙风洞中参数测量本身受到高温非平衡效应影响，单纯依靠实验测量不足以确定详细的风洞自由流参数。本文以JF-10高焓激波风洞为背景。通过喷管-试验段-测量仪模型非平衡流场的连贯计算，开展自由流参数测量的数值重建。在比较分析测量仪模型绕流场的计算结果和实验测量值的基础上，结合喷管流场的数值模拟结果，共同确定高焓风洞的详细自由流参数。

英文摘要：

It is difficult to determine the simulative parameters of a new high enthalpy tunnel merely by measurements because the measurements themselves are affected by the high temperature nonequilbrium effects. Taking the high enthalpy shock tunnel JF-10 as an example, the free-stream measurements taken in the test section are numerically rebuilt through calculating the nozzle flow field and the flow fields around the measurement probes sequentially. The detail free-stream properties in JF-10 tunnel are determined by integrating the numerical solution of the nozzle flow field with the free-stream measurement values and the results of the numerical rebuilding of the measurements.
