Simulation results for hydrogen flames in counter-current nozzles triggering the global instability phenomenon: effect of steam dilution

Research data related to the publication "Investigation of steam-diluted hydrogen combustion in a counter-current nozzle configuration using LES"The study concerns a co-axial counter-current jet configuration conceptualized as a wet hydrogen/air injector. Such an injector system induces a flow pattern beneficial for triggering global instability near a nozzle lip. Using high-fidelity LES, we explore how global instability alter the flame dynamics through adjustments in the strength of the counter-current flow for selected dilution level. In particular, we present regimes for lifted flames to mitigate hydrogen corrosion risk and enhance combustion efficiency.The readme file contains sorted filenames linked to the figures from the article.For details on file formats please refer to the readme file and documentation: https://www.tecplot.com/2016/09/16/tecplot-data-file-types-dat-plt-szplt/This work was supported by the National Science Center (Grant No. 2022/47/D/ST8/01902).
