    Entropy-Constrained Machine Learning with Residual Data Augmentation for Modeling Chemical Kinetics

    Okezzi Ukorigho, Opeoluwa Owoyele

    physics.flu-dyn · cs.LG

    We present a physics-constrained machine learning framework for accelerating the direct numerical simulation (DNS) of turbulent reacting flows. The model replaces the direct evaluation of detailed chemical source terms with a surrogate that predicts reaction rates from a reduced thermochemical state. To improve physical consistency, the second law of thermodynamics is incorporated as a training constraint by enforcing non-negative entropy...
