TDACChemistryModel: New chemistry model providing Tabulation of Dynam…
…ic Adaptive Chemistry Provides efficient integration of complex laminar reaction chemistry, combining the advantages of automatic dynamic specie and reaction reduction with ISAT (in situ adaptive tabulation). The advantages grow as the complexity of the chemistry increases. References: Contino, F., Jeanmart, H., Lucchini, T., & D’Errico, G. (2011).

CFD simulations using the TDAC method to model iso-octane combustion for a large range of ozone seeding and temperature conditions in a single cylinder HCCI engine. Fuel, 137, 179-184. Two tutorial cases are currently provided: + tutorials/combustion/chemFoam/ic8h18_TDAC + tutorials/combustion/reactingFoam/laminar/counterFlowFlame2D_GRI_TDAC the first of which clearly demonstrates the advantage of dynamic adaptive chemistry providing ~10x speedup, the second demonstrates ISAT on the modest complex GRI mechanisms for methane combustion, providing a speedup of ~4x. More tutorials demonstrating TDAC on more complex mechanisms and cases will be provided soon in addition to documentation for the operation and settings of TDAC. Also further updates to the TDAC code to improve consistency and integration with the rest of OpenFOAM and further optimize operation can be expected. Original code providing all algorithms for chemistry reduction and tabulation contributed by Francesco Contino, Tommaso Lucchini, Gianluca D’Errico, Hervé Jeanmart, Nicolas Bourgeois and Stéphane Backaert. Implementation updated, optimized and integrated into OpenFOAM-dev by Henry G. Weller, CFD Direct Ltd with the help of Francesco Contino.
