  • COMPUTATIONALLY EFFICIENT REDUCED KINETICS METHODOLOGIES FOR JET FUELS
    Publication number: 20240169119
    Abstract: A method for implementing a modeling tool that generates optimized reduced kinetic models for given operating conditions and a numerical scheme to speed-up kinetic evaluation of turbulent-chemistry coupling during CFD simulations. The tool is capable of predicting ignition and flameholding phenomenon for most propulsion systems, including gas turbine applications. A lumped-parameterization based optimization scheme may generate multi-step quasi-global kinetic models using laminar flame speed as the target data. This scheme may be further extended to include optimization of emission predictions such as CO and NOx.
