Problems solved by technology

However, since every method of mechanism simplification currently simplifies the mechanism from a certain aspect or angle, which has certain working condition limitations and mechanism dependence, researchers in this field are still exploring the details of the detailed mechanism at this stage. For essential problems, improve the speed of simplified mechanism methods, use more intelligent optimization or search algorithms, obtain high-precision simplified mechanisms that do not depend on human experience, and explore the backbone reaction path process of the combustion process

Abstract

The invention discloses a hydrocarbon fuel mechanism simplification method which comprises a step S1 of adopting a direct relation graph method based on error propagation to perform mechanism simplification from the angle of component coupling; a step S2 of adopting a main component analysis method to perform mechanism simplification from the angle of elementary reaction; a step S3 of adopting a linear isomer lumping method to perform mechanism simplification from the angle of component isomers; a step S4 of adopting a sensibility analysis method to correct kinetic parameter values; and performing mechanism simplification from angle of perturbation factors. According to the hydrocarbon fuel mechanism simplification method, on the premise of maintaining small scale dimension of the mechanism, a mechanism computational accuracy effect is ensured, and computer automatic mechanism simplification thought is implemented basically.

Description

technical field [0001] The invention relates to the field of combustion reaction kinetics, in particular to a method for simplifying the mechanism of hydrocarbon fuels. Background technique [0002] With the development of computer technology, numerical simulation method has become one of the important means of reacting flow analysis, which has greatly promoted the development of combustion theory, new burner and new fuel technology. To achieve accurate quantitative predictions of chemical reactions, detailed chemical reaction mechanisms must be incorporated into numerical simulations of reacting flows. The detailed chemical reaction mechanism consists of elementary components and reactions involving elementary components. As the number of carbon atoms in carbon-containing fuels increases, the number of components and elementary reactions included in the detailed chemical reaction mechanism also increases rapidly, which leads to an increase in the amount of numerical simula...
