Investigation of Sensitivity of Complex Reacting Systems to Chemical Reaction Rates

Abstract

Two methods have been developed to investigate the sensitivity of numerical solutions of sets of coupled nonlinear differential equations to uncertainties in the modeling parameters entering the calculations of chemical kinetics. The methods determine the sensitivity by performing the calculations for a set of values of the modeling parameters within the estimated uncertainty range of each. The methods are demonstrated for two chemical reaction systems: The N-O system, and the H-O system.
