Numerical results for hydrogen auto-ignition in oxygen–nitrogen and oxygen–water vapor oxidizers: analysis in mixture fraction space and 3D turbulent flow

Research data related to the publication "A Comparative Study of the Hydrogen Auto-Ignition Process in Oxygen–Nitrogen and Oxygen–Water Vapor Oxidizer: Numerical Investigations in Mixture Fraction Space and 3D Forced Homogeneous Isotropic Turbulent Flow Field".This dataset contains numerical simulation results of the auto-ignition process of hydrogen in a hot oxidizer stream composed of oxygen–nitrogen and oxygen–water vapor mixtures, with nitrogen or water vapor mass fractions ranging from 0.1 to 0.9. The oxidizer temperature varies between 1100 K and 1500 K, while the hydrogen stream is maintained at 300 K.The simulations were conducted using two approaches:In 1D mixture fraction space with the Unsteady Flamelet ModelIn a 3D forced homogeneous isotropic turbulent flow field using Large Eddy Simulation (LES) combined with the Eulerian Stochastic Field (ESF) combustion modelThe simulation results are provided in files named Fig*.dat, where each file corresponds to a figure from the associated publication. The readme.txt file includes a sorted list of filenames linked to the respective figures. The meaning of the data contained in each file is also explained in the readme.txt.For more information about the .dat file format, please refer to the Tecplot documentation:https://www.tecplot.com/2016/09/16/tecplot-data-file-types-dat-plt-szplt/The first author (LC) gratefully acknowledges funding from the Polish National Science Center (Grant No. 2020/39/B/ST8/02802), which supported the PhD fellowship underlying this research. The simulations were performed using high-performance computing resources provided by PL-Grid and PCSS computing centers.
