Ammonia is emerging as a very convenient hydrogen- and energy-carrier in the context of present efforts to curb carbon emissions from the power-generation and transport sectors. As opposed to hydrogen, the properties of ammonia make it significantly

The present work introduces an annular combustion chamber operated at intermediate pressures. The combustor is operated with CH-H blends leading to a variety of azimuthal combustion instabilities. The influence of the hydrogen content, the air mass f

This article deals with the symmetry breaking of azimuthal thermoacoustic modes in annular combustors. Using a nominally symmetric annular combustor, we present experimental evidence of a predicted spontaneous reflectional symmetry breaking, and also

Ammonia is emerging as a very convenient hydrogen- and energy-carrier chemical that, in the context of present efforts to curb carbon emissions from the power-generation and transport sectors, can be manufactured from both green hydrogen, generated f

Self-excited thermoacoustic instabilities in symmetric annular combustion chambers typically give rise to spinning, standing and mixed azimuthal modes which are time-varying in nature and occur in a highly noisy environment due to turbulent combustio

In this study, the heat release rate (HRR) response during self-excited azimuthal thermoacoustic instabilities in a pressurized annular combustor is investigated for hydrogen/methane blended flames. The equivalence ratio and hydrogen power fraction w

The present article experimentally investigates the triggering and transient growth of azimuthal instabilities in a pressurized laboratory-scale annular combustor featuring 12 methane/hydrogen flames, as the equivalence ratio is ramped up and down. T

In jet engines and gas turbines, the annular shape of the combustion chamber allows the appearance of self-oscillating azimuthal thermoacoustic modes. We report experimental evidence of a new type of modal dynamics characterised by periodic switching

To maximise power density practical gas turbine combustion systems have several injectors which can lead to complex interactions between flames. However, our knowledge about the effect of flame-flame interactions on the flame response, the essential
