Computationally efficient implementation of combustion chemistry using in situ adaptive tabulation
Combustion Theory and Modelling, 1997A computational technique is described and demonstrated that can decrease by three orders of magnitude the computer time required to treat detailed chemistry in reactive flow calculations. The method is based on the in situ adaptive tabulation (ISAT) of the accessed region of the composition space - the adaptation being to control the tabulation errors.

ZIB Report, 2008
In this paper we propose a technique for a priori turbulent flame speed tabulation (TFST) for a given parameter space in standard combustion- regime diagrams. It can be used as a subgrid-scale (SGS) model in Large Eddy Simulation (LES). In a first step, stationary laminar flamelets are computed and stored over the progress variable following the ideas ...

Efficient slow manifold identification for tabulation based adaptive chemistry
2007We present a tabulation strategy for the numerical integration of chemical reacting flow processes on the basis of a reduced (non-stiff) model of the original set of ODEs. Both the tabulation and the identification of the reduced model are adaptive and are based on the Computational Singular Perturbation (CSP) method.

Tabulation of Dynamic Adaptive Chemistry for internal combustion engine simulations
2010Detailed kinetic mechanisms can describe the oxidation of complex fuel mixtures over a wide range of operating conditions. Including these mechanisms in computational fluid dynamics simulations has, however, a computational cost that is, in most case, not affordable. Several methods aim at reducing this computational cost.
