New HERMES publication: “Assessment of Global and Detailed Chemical Kinetics in Supercritical Combustion for Hydrogen Gas Turbines”

July 8, 2025

University of Twente, in collaboration with Wrocław University of Science and Technology, have released a new, open access paper on the “Assessment of Global and Detailed Chemical Kinetics in Supercritical Combustion for Hydrogen Gas Turbines”. The study explore the use of a reduced global reaction mechanism versus the detailed FFCM-1 model for hydrogen combustion with supercritical CO₂ and argon as diluents. Through CFD simulations in both simplified and realistic combustor geometries, analysis suggests:

  • Relative errors under 4% compared to detailed chemistry
  • Accurate capture of key behaviors like buoyancy-driven flame asymmetry
  • Validation of global models as efficient tools for simulating supercritical combustion
