Numerical Estimation in Combustion Kinetics.

Abstract

In this article we apply this most useful approximation in the solution of ordinary differential equations -- the steady state approximations -- to combustion applications, for the first time. The reasons this approximation has not worked in the past are detailed. Basically, they have not worked because of the very stiff nature of the system in which the stiff 'boundary layer' occurs internal to the solution time domain and significantly complicates the analysis. The saved time with implementing the steady approximation is indicated to be quite significant and has potential to allow numerical solution of real combustor models for which presently it is too time consuming to solve. Generalization is needed for kinetics equation sets of arbitrary size. (Author)
