Abstract
This study, conducted within the HOPE (Hydrogen Optimized multi-fuel Propulsion system for clean and silEnt aircraft) project, examines how kerosene-hydrogen fuel blends affect flame topology in a multi-fuel combustor designed to advance hydrogen powered aviation. High-fidelity Stress-Blended Eddy Simulations were performed to reproduce experimental testing conducted at the Delft University Sustainable Propulsion Lab, and results were compared against available experimental data to assess the flame topology across pure hydrogen, pure kerosene, and multi-fuel cases. Additionally, lower-fidelity simulations were used to evaluate combustor performance under limiting engine operating conditions, specifically a hydrogen-only take-off scenario.
