高超声速粘性干扰效应相关性研究

Study on Correlation of Hypersonic Viscous Interaction

探讨了高超声速粘性干扰效应的相关性理论,采用CFD数值模拟方法对轨道器再入阶段的粘性干扰效应进行了研究,以此为基础考察了粘性干扰相关参数′∞的关联特性。对计算结果的分析表明:ν-′∞能够将轨道器外形气动力的地面风洞试验数据和飞行试验数据进行有效关联,从而为建立轨道器外形再入气动力天地换算方法奠定了基础。

In this paper, the correlation theory about the hypersonic viscous interaction was discussed and the viscous interaction effect on reentry orbiters was studied by a CFD simulation method. The correlation parameter of viscous interaction V∞ was examined hereby. The analyses on the compute result indicate that the correlation parameter of viscous interaction V∞ can correlate the ground experiment data with flight data effectively, which give the foundation to the establishment of the correlation method of ground experiment data with flight data.
