Application of CSP to the Reduction of a Complex Combustion Reaction System
Abstract:
A numerical study based on computational singular perturbation (CSP) in a methane/air premixed combustion system was undertaken. This method splits reaction spaces to eliminate stiffness, identifies quasi-steady-state (QSS) species by analyzing CSP pointer locally and integrally as well as simplifying algebraic relations and differential equations by using two CSP indexes. Finally, a 15-step globally reduced mechanism was constructed based on CSP analyses in a premixed methane/air combustion system. The 15-step reduced mechanism was tested and verified using Sandia’s PREMIX. Advantages of the CSP method are discussed. A new method for analyzing the reduced mechanismmay be used for more complex combustion systems.
