Journal ArticleDOI
Simplifying chemical kinetics: Intrinsic low-dimensional manifolds in composition space
Ulrich Maas,Stephen B. Pope +1 more
TL;DR: In this article, a general procedure for simplifying chemical kinetics is developed, based on the dynamical systems approach, in contrast to conventional reduced mechanisms no information is required concerning which reactions are to be assumed to be in partial equilibrium nor which species are assumed to remain in steady state.
Book
Combustion: Physical and Chemical Fundamentals, Modelling and Simulation, Experiments, Pollutant Formation
TL;DR: The Navier-Stokes Equations for Three-dimensional Reacting Flows (NSFE) as discussed by the authors describe the Navier Stokes equation for three-dimensional reacting flows.
Journal ArticleDOI
Ignition processes in hydrogenoxygen mixtures
Ulrich Maas,J. Warnatz +1 more
TL;DR: In this article, a detailed reaction mechanism and a multispecies transport model were used to simulate the explosion limits of the hydrogen-oxygen system and the minimum ignition energies for various mixture compositions, pressures, radii of the external energy source and ignition times.
Journal ArticleDOI
Implementation of simplified chemical kinetics based on intrinsic low-dimensional manifolds
Ulrich Maas,Stephen B. Pope +1 more
TL;DR: In this paper, a general procedure for simplifying chemical kinetics and its use in reacting flow models is developed, which is based on the dynamical systems approach, and results are presented for the CO/H2/air system both for a simple homogeneous closed system and a flow reactor.
Journal ArticleDOI
The extension of the ILDM concept to reaction–diffusion manifolds
Viatcheslav Bykov,Ulrich Maas +1 more
TL;DR: In this paper, the method of simplifying chemical kinetics based on Intrinsic Low-Dimensional Manifolds (ILDMs) is modified to deal with the coupling of reaction and diffusion processes.
