摘要

本研究的目的是表征激波与平行六面体障碍物的相互作用。对60种不同障碍物尺寸配置下的激波特性进行了量化。在引入新参数的情况下，利用这些实验测量值，写出平行六面体障碍物到达时间和下游最大超压的演化规律。这些定律的准确性令人满意。然后，将最大超压规律与文献中的实验结果进行了比较。尽管障碍物几何形状或实验设置不同，但这些实验数据与最大超压定律很好地吻合。

Evaluation of shock wave properties interacting with a parallelepipedal obstacle

The aim of this study was to characterize the interaction of a shock wave with a parallelepipedal obstacle. Shock wave properties were quantified downstream of sixty configurations with different obstacle dimensions. With the introduction of new parameters, these experimental measurements were used to write evolution laws for the arrival time and the maximum overpressure downstream of a parallelepipedal obstacle. The accuracy of these laws was satisfactory. Then, the maximum overpressure law was compared with experimental measures from the literature. Despite differences in the obstacle geometry or experimental setup, these experimental data are in good agreement with the maximum overpressure law.
