The global quasi-linearization (GQL) is used as a method to study and to reduce the complexity of mathematical models of mechanisms of chemical kinetics. Similar to standard methodologies, such as the quasi-steady-state assumption (QSSA), the GQL met

A different methodology for implementing the standard mechanism reduction technique directed relation graph (DRG) is presented and applied to develop a new skeletal mechanism for ethanol. Two combustion processes, ignition delay time and flame speed,

Numerical simulations involving detailed kinetic reaction mechanisms of combustion for conventional fuels are associated with computational costs prohibitive and, therefore, a lot of effort for obtaining reduced kinetic mechanisms has been observed.

Simulation of turbulent flames using detailed chemical mechanisms is still a challenge in numerical combustion due to the large number of species and the stiffness of the system of governing equations. In this sense, strategies to reduce the size of

Combustion simulations involve the modeling of chemical kinetics, and due to the complexity of detailed mechanisms, chemistry reduction techniques are necessary. One model reduction strategy is the reaction-diffusion manifold (REDIM) method, and to o
