Premixed lean hydrogen-air flames exhibit instabilities due to hydrodynamic instabilities but
also thermo-diffusive instabilities. However, in the case of ammonia/hydrogen blends, the …

In this study, a three-dimensional, high fidelity LES of a fully premixed, lean hydrogen-air
deflagration, in a confined and obstructed channel is performed. The experimental …

Even in the laminar regime, lean H 2-air flames are prone to intrinsic Thermo-Diffusive (TD)
instabilities which contribute to flame acceleration. Applying the Thickened Flame (TF) …

The development of low NO x hydrogen (H 2) burners is crucial for the sustainability target of
the power/propulsion sector. However, the technical difficulty of burning H 2 at low NO x …

This study explores the complex mechanisms driving flame acceleration (FA) in hydrogen/air
mixtures with transverse stratification, using high-fidelity 3-D Large Eddy Simulations (LES) …

Due to the high costs associated to experimental testing of hydrogen (H 2) explosions,
numerical simulations play an essential role in the design of safe industrial systems. In this …

With the introduction of carbon-free fuels and their rapid implementation, accurate
combustion models are needed to design decarbonized engines, gas turbines or burners …

Hydrogen (H 2) has become a key in the decarbonation process of the aeronautical field
and new gaseous injection systems must be designed to suit hydrogen's specific properties …

Abstract High-fidelity Large-Eddy Simulations (LES) are used to study the ignition dynamics
of two fuel/air mixtures with distinct Lewis numbers L e, unveiling the impact of preferential …

This paper establishes a data-driven modeling framework for lean Hydrogen (H2)-air
reaction rates for the Large Eddy Simulation (LES) of turbulent reactive flows. This is …
