The dynamics of V-shape swirled lean premixed methane/air flames enriched with hydrogen
is examined for two injection schemes. The response of the flames submitted to harmonic …

The frequency response of three lean methane/air flames submitted to flowrate perturbations
is analyzed for flames featuring the same equivalence ratio and thermal power, but a …

Constructive interference between heat release rate and acoustic perturbation is
responsible for the growth of acoustic pressure amplitudes, leading to high-amplitude …

Effects of swirl divergence cup and the central bluff body on premixed flame response with
external excitation are experimentally investigated. Flame transfer functions (FTFs) …

Ammonia is a promising hydrogen and energy carrier but also a challenging fuel to use in
gas turbines, due to its low flame speed, limited flammability range, and the production of …

Flame dynamics in the presence of transverse acoustic fluctuations is an aspect of relevance
to modern annular combustors. In particular, it is a key element underlying the occurrence …

Premixed low swirling flames (methane–air and hydrogen–methane–air) are experimentally
investigated for three different regimes. Stable, local transient to instability and limit cycle …

This numerical study investigated the effects of the fresh mixture temperature on
thermoacoustic instabilities in a lean premixed swirl-stabilized combustion chamber by …

The combustion characteristics of propane/air bluff-body stabilized swirl diffusion flames
within the turbulent regime are studied experimentally to determine the effect of the swirl …

The frequency response of premixed swirled flames is investigated by comparing their
Transfer Function (FTF) between velocity and heat release rate fluctuations. The …
