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.
