GQL-RedChem: A MatLAB-based tool for the model reduction for chemical kinetics based on the Global Quasi-linearisation (GQL) approach

The Global Quasi-linearization (GQL) approach has been developed for the dimension reduction of the chemical kinetics, which aim at speeding up the numerical simulation of reacting flows. GQL-RedChem is a MatLAB-based package that integrates the homogeneous reacting systems, formulated mathematically as a system of Ordinary Differential Equations (ODEs). The package provides with an approximation of the fast/slow decomposition linear basis, describing a reacting source term by a system of Differential Algebraic Equations (DAEs). The GQL method can be applied for reacting systems with any complexity, and the GQL decomposition basis can be generated in a generic and automatic manner.
