Systematic simplification of chemical kinetic mechanisms with DRG and CSP methods abstract
The algorithm of directed relation graph (DRG)recently developed for skeletal mechanism reduction is extended to overall linear time operation,thereby greatly facilitating the computational effort in mechanism reduction,particularly for those involv ing large mechanisms.This algorithm is applied to a spatially homogeneous constant-pressure autoignition of methane combustion and result are compared with CSP method.It is observed that the accuracy of skeletal mechanisms is equivalently bounded by t he user-specified error threshold value.DRG method because of directly eliminate unimportant species instead of elementary reactions,computationaly is more efficient.
