Being burnup analytical manner and the manner which calculates the burnup analytical device

摘要

PROBLEM TO BE SOLVED: To prevent deterioration of calculation accuracy in a nonequilibrium combustion state while using the chemical equilibrium method.;SOLUTION: A combustion analysis method for numerical analysis of combustion includes: a first step of calculating generation amount of one or a plurality of first chemical species which is part of chemical species related to combustion of an analysis target in accordance with the algorithm based on the chemical equilibrium method; a second step of calculating reaction velocity by the combustion of one or plurality of second chemical species which is the other part of the chemical species related to the combustion in accordance with the algorithm based on the reaction kinetics; and a third step of calculating generation amount of the second chemical species by substituting the reaction velocity calculated in the second step to the conservation formula of the second chemical species.;COPYRIGHT: (C)2010,JPO&INPIT
