Numerical Viscous Shock Layer Solution to the Hypersonic Chemically Equilibrium Flows

The viscous shock layer numerical solutions to the hypersonic chemicallyequilibrium laminar flows are presented. These results are obtained by the spatialmarching method. The comparision with the results of reference 8 is made toassess the accuracy of the present method. This method, which fully couplesthe governing equations, gives the accurate and stable results, These resultsare comparedwell with those from reference 8. A chemical equilibrium model, whick is based on the Free-Energy-Minimumprinciple, is used. For this model, it is convenient to choose the species. Thesteepest descent method is used to make the chemical ecuilibrium model easilyimplemented.
