某组合体模型气动热数据相关性研究

为进行高超声速气动热数据相关性研究, 选取了一平板-锥组合体模型为研究对象, 开展不同缩比模型的风洞试验, 分别使用3种不同方法进行气动热试验数据的相关性研究.研究结果表明, 使用正激波后Reynolds数Re_ns和修正的黏性干扰系数V*/S_w可以将不同缩比模型不同来流条件下的Stanton数进行较好的关联, Stanton数与正激波后Reynolds数Re_ns成反比例关系, 与修正的黏性干扰系数V*/S_w成正比例关系.最后基于相关性研究结论和理论分析, 提出了一种模型表面传热现象的数学模型. 

Correlation of Aerodynamic Heating Data of a Combination Model

The aero-thermal measurements of a series of plate-cone configuration models with various scales were obtained in the wind tunnel tests and analyzed by three different methods to investigate the hypersonic aero-thermal correlation. The results show that the Stanton number with different model scales and freestream parameters could be well correlated by Reynolds number behind the normal shock wave Re_ns and the modified viscous interaction parameter V*/S_w, and the Stanton number is inversely proportional to Re_ns and proportional to V*/S_w. Finally, based on the correlation results and theoretically analyses, a mathematics model of the heat transfer around the vehicle surface was established.
