An Optimization Approach to Kinetic Model Reduction for Combustion Chemistry

Abstract: Model reduction methods are relevant when the computation time of a full convection-diffusion-reaction simulation based on detailed chemical reaction mechanisms is too large. In this article, we review a model reduction approach based on optimization of trajectories and show its applicability to realistic combustion models. As most model reduction methods, it identifies points on a slow invariant manifold based on time scale separation in the dynamics of the reaction system. The numerical approximation of poin… Show more

“…The work of Ginoux et al is of particular significance in the context of this paper, it supported our inspiration to work on topics presented here although we have been concerned with differential geometry ideas in the context of slow invariant manifolds since some years [32] without knowing about Ginoux's work. Our model reduction technique is based on a variational principle by using a trajectory-based optimization approach is proposed by Lebiedz et al [27,31,32,33,35,34], which is supposed to be applied to kinetic models in combustion chemistry [28,29]. The recently published work of Lebiedz and Unger [30] discusses and exploits common ideas and brings together concepts of several model reduction approaches.…”

“…Other constructive methods are based on the iterative solution of the partial differential equations defining the slow manifold (e.g. 13 ), on finding the invariant manifold connecting the equilibrium state to (usually unphysical) saddle points 5,14 , and on trajectoryoptimization variational approaches 12,15 , which was recently applied for the construction of a two-dimensional SIM for syngas combustion 16 .…”
