摘要
本文提出了一个高超声速非烧蚀钝体化学非平衡尾流流场的简化模型和简化的空气化学模型。应用该模型计算尾流的积分电子密度。计算结果与实验数据符合得很好。在此基础上,以P_∞D_N=375mmHg·mm为例,初步论证了尾流双尺度律的适用程度与范围,为弹道靶模型实验提供正确的导向。
A simplified flow field model and simple air chemical model for the chemical nonequilibrium trailing wakes of hypersonic non-ablating blund-body are presented. The models are applied to calculate the integrated electric desnsity . The calculated results are compared to the wake measurements in the ballistic region. the agreement between them is good. Based on the results, the applicability of binary scaling law is researched to fllow the example of P∞·DN = 375.It provides exact direction for ballistics range models expeimental measurement.
