Development of a finite rate chemistry solver with tabulated dynamic adaptive chemistry

The present project falls under the adaptive chemistry category and aims to develop a numerical framework for the study of turbulent flames at various regimes using high-fidelity numerical simulations with on-the-fly adaptive kinetics. The chemistry reduction process is based on the Path Flux Analysis (PFA) enforcing Adaptive Chemistry (AC) based on local conditions.

State of the art reduction models and the proposed model are tested in canonical combustion problems. The proposed model is found to predict solutions with the same accuracy as the state of the art models in steady-state cases and performs better in transient cases due to its nature of chemistry reduction which makes it applicable to a variety of combustion problems without any tuning. Computationally the proposed model was found to be between 5 to 20 % faster for specific cases than the respective reference case with no chemistry reduction.
