| 摘 要： | 1. IntroductionWe consider steady inviscid hyPersonic flow of air about a concave corner including chendcalreaction effects. Computation of nonequllibrium flow is duncult because of the steep gradielltsbehind the shock and an entroPy layer near the body For many cases the time scale of theChemical reactions is 1arger than, or close to, the time scale of the origina1 meChanical problemand the equllibrium chendstry mode1 is not realistic. Therefore, it is necessary to eva1uate thekinetics of c…

| Abstract: | This paper is devoted to computation of hypersonic flow of air with chemical reactions over concave corners. A technique combining smooth transformation of domain and im- plicit difference methods is used to overcome numerical dimculties associated with the lack of resolution behind the shock and near the body. The implicit treatment of right hand side terms is also an important part of our method. |
