Abstract

The Computational Singular Perturbation (CSP) method is employed (1) in the modeling of a homogeneous isothermal reacting system and (2) in the numerical simulation of the chemical reactions in a hypersonic fiowfield. Reduced and simplified mechanisms arc constructed. The solutions obtained on the basis of these approximate mcchanisms arc shown to be in very good agreement with the exact solution based on the full mechanism. Physically meaningful approximations arc derived. It is demonstrated that the deduction of these approximations from CSP is independent of ihe complexity of the problem and requires no intuition or experience in chemical kinetics.
