Fun challenge: Actually, there were five scientists from STFS at the conference. Can you spot the fifth one in the pictures?
Our Contributions & Key Discussions:
We contributed to key topics including turbulent hydrogen combustion, dual-fuel combustion, soot modeling, and thermo-acoustics.
What stood out for me personally: bridging fundamental and applied research through high-performance computing.
Philipp Koob presented two papers:
- „Comprehensive Modeling of the Cause-and-Effect Chain in Aero-Engine Combustor Simulations: From Primary Breakup to Soot Formation“
- From primary breakup to soot formation: exploring sensitivities across the full modeling chain in aero engines.
- „Exploring Soot Pathways: High-Fidelity LES Investigation of Soot Formation and Oxidation in RQL Combustion Systems Under Real Conditions“
- Introducing a region-wise combustor classification to identify key mixing and quenching effects.
Florian Uetrecht:
- „Assessment of a Hybrid LES-CAA Method for Predicting Flame Responses in Swirl-Stabilized Combustion under various acoustic excitations“
- Validating a hybrid LES-CAA approach for flame transfer function prediction under acoustic forcing—benchmarking against experimental data.
Vinzenz Schuh:
- „An Extended Artificially Thickened Flame Model for Turbulent Hydrogen and Hydrogen-Enriched Flames With Intrinsic Instabilities Under Gas Turbine Relevant Conditions“
- Presenting a new efficiency function to capture thermo-diffusive instabilities in lean H₂ flames—enabling accurate predictions across relevant gas turbine conditions.
Sofya Buro:
- „Development and Assessment of Dual-Fuel Capabilities in Next-Generation Aero-Engine Injectors for Hydrogen and SAF“
- Demonstrating a CFD-based optimization workflow for H₂/SAF dual-fuel injectors—assessing retrofitting potential while meeting current emission regulations.
Global Networking at Its Best in the City of Blues:
We had inspiring conversations with colleagues from all over the world on new future collaborations.
…and yes, great local blues music to top it off!
