摘要: |
本文给出了层流化学平衡粘性激波层方程对于细长解析体的数值解。这些求解结果是通过空间步进方法得到的,并且与参考文献里的计算结果作了比较,以估价该方法的精确度。结果表明,这种控制方程完全耦合求解的方法能够给出相当精确和稳定的结果,这些结果与参考文献的计算结果相当吻合。 |

Abstract: |
The viscous shock layer numerical solutions to the hypersonic chemically equilibrium laminar flows are presented. These results are obtained by the spatial marching method. The comparision with the resu1ts of reference 8 is made to assess the accuracy of the present method. This method,which fully couples the governing equations,gives the accurate and stable results. These results
are comparedwel1 with those from reference 8. A chemical equilibrium model,whick is based on the Free-Energy-Minimum principle,is used. For this model,it is convenient to choose the species. The steepest descent method is used to make the chemical ecuilibrium model easily implemented. |
