The description of chemically reacting systems leads very often to reaction mechanisms with
far above hundred chemical species (and, therefore, to more than a hundred partial …

The quasi steady state and partial equilibrium approximations are analysed in the context of
a system of nonlinear differential equations exhibiting multiscale behaviour. Considering …

Numerical simulation of turbulent reacting flow is still a challenging task. For the efficient
computational simulation and applicability for technical systems, simplifications for both …

Increases in both chemical kinetics knowledge and the capacity of computers have led to the
availability of very large detailed kinetic mechanisms for many problems. These …

In the framework of the classical theory of Singularly Perturbed Systems (SPS) there exist
two main types of invariant manifolds, ie fast and slow manifolds with their own intrinsic …

A recently developed automatic reduction method for systems of chemical kinetics, the so-
called Global Quasi-Linearization (GQL) method, has been implemented to study and …

Determining the thermal profile of ignition is important because the desired ignition behavior
varies with the objective. For example, extended ignition prolongs the time that the engine …

Nowadays the mathematical description of chemically reacting flows uses very often
reaction mechanisms with far above hundred or even thousand chemical species (and …

In this work, two different reduction methods for simplification of chemical kinetics, the Global
Quasi-linearization (GQL) and the Directed Relation Graph (DRG), are implemented and …

ABSTRACT The Global Quasi-Linearization (GQL) method for model reduction of chemical
kinetics is applied to describe the very sensitive regime of the onset of the thermal-diffusion …
