The effect of hydrogen addition on the amplitude and harmonic response of azimuthal instabilities in a pressurized annular combustor
Indlekofer, Thomas; Ahn, Byeonguk; Kwah, Yi Hao; Wiseman, Samuel; Mazur, Marek; Dawson, James; Worth, Nicholas (Peer reviewed; Journal article, 2021)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 ... -
Large volume scanning laser induced fluorescence measurement of a bluff-body stabilised flame in an annular combustor
Govender, Dirren; Wiseman, Samuel; Dawson, James; Worth, Nicholas (Journal article; Peer reviewed, 2022)This study outlines a variant of three-dimensional OH planar laser-induced fluorescence and its application in characterising a single bluff body stabilised flame inside a 12 burner annular combustor. In this variant of ... -
Scaling and prediction of transfer functions in lean premixed H2/CH4-flames
Æsøy, Eirik; Aguilar, Jose; Wiseman, Samuel; Bothien, Mirko R.; Worth, Nicholas; Dawson, James (Journal article, 2020)Features of the flame transfer function (FTF) are characterized for turbulent, non-swirled, bluff body stabilized “M” flames for different hydrogen and methane blends including pure hydrogen flames. An increase in the ...
