An automatic procedure for the simplification of chemical kinetic mechanisms based on CSP
An algorithm is developed to generate simplified (skeletal) kinetic mechanisms from a given detailed one. The algorithm is able to replicate the dynamics of a user-specified set of species (chosenExpand

An efficient iterative algorithm for the approximation of the fast and slow dynamics of stiff systems
The relation between the iterative algorithms based on the computational singular perturbation (CSP) and the invariance equation (IE) methods is examined. Expand

Structure of n-heptane/air triple flames in partially-premixed mixing layers
Results of a detailed numerical analysis of an n-heptane/air edge flame are presented. The equations of a low-Mach number reacting flow are solved in a two-dimensional domain using detailed modelsExpand

The G-Scheme: A framework for multi-scale adaptive model reduction
We propose a numerical technique consisting of an algorithmic framework, named the G-Scheme, to achieve multi-scale adaptive model reduction along-with the integration of the differential equations (DEs). Expand

Reactive and reactive-diffusive time scales in stiff reaction-diffusion systems
Two different sets of time scales arising in stiff systems of reaction-diffusion PDEs are examined; the first due to the reaction term alone and the second due to the interaction of the reaction andExpand

On the numerical integration of multi-dimensional, initial boundary value problems for the Euler equations in quasi-linear form
A matricial formalism to solve multi-dimensional initial boundary values problems for hyperbolic equations written in quasi-linear based on the λ scheme approach is presented. The derivation isExpand

Dynamical system analysis of ignition phenomena using the Tangential Stretching Rate concept
Abstract We analyze ignition phenomena by resorting to the stretching rate concept formerly introduced in the study of dynamical systems. We construct a Tangential Stretching Rate (TSR) parameter byExpand
