Combustion Modelling

for Gas Turbines

New approaches for combustion in gas turbines , industrial burners , and reciprocating engines adapted to hydrogen and / or ammonia fuels . Work includes early-stage concept development , improving understanding , and improving engineering modelling for these challenging fuels .

Competitive Advantage

• Experimental facilities , including multiple engines , optical and metal , high-pressure combustion chambers , and optical diagnostics
• In-house direct numerical simulation ( DNS ) codes that scale to millions of CPU-cores , complemented by large eddy simulation ( LES )
• Deep understanding of hydrogen and ammonia combustion characteristics specific to issues associated with gas turbines , burners and diesel engines

Impact

• Proof of concept for new combustion approaches adapted to hydrogen and ammonia combustion

Capabilities and Facilities

• Multiple engine test beds complemented by highpressure combustion chambers
• Extensive optical measurement capabilities
• Highly scaling DNS and LES codes and access to significant CPU time allocations
