Using high-performance computing in the simulation of the combustion process in liquid-fuel engines aids in obtaining a better understanding of the complex multiphase, multi-physics, and multiscale nature of this phenomenon to improve combustion efficiency and reduce emissions. Combustion behavior is strongly linked to the evaporation of the fuel droplets during the atomization process and their mixing with air in high-pressure engines. We perform simulations of transient and high-pressure reacting turbulent flows using detailed chemical mechanisms. To reduce the cost of 3D and high-fidelity reacting flow simulations, our group develops novel machine-learning-based tools to reduce the number of reactions and species included in detailed chemistry mechanisms that tend to slow down the simulations.
