| 摘 要： | 建立了一维激波结构模型,对Burnett方程进行简化得到STNM方程,通过在均匀网格上采用二阶空间差分对无量纲化后的STNM方程进行数值计算,得到了激波内部参数变化剖面。以氩气为研究对象对一维激波结构进行数值分析计算。结果表明随着马赫数增大,omage数对于激波结构的影响增大,在相同omage数条件下,马赫数变化对激波内部参数变化的影响显著。

| Abstract: | The model of 1D shock wave structure is established and Burnett equations are predigested to STNM. Numerical analysis is computed with the STNM equations and the change of parameters in shock wave structure is found. The 1-D shock wave structure is calculated using Ar as the working object. The result shows that with the increasing of Ma number, the effect that omage number has on shock wave structure is more and more clearly. When they have the same omage number, Ma would make a significant effect on the c... |
