Influence of equivalence ratio and hydrogen addition on thermoacoustic instabilities in premixed methane and propane flames in vertical tubes

This research examines the behavior of premixed flames within a vertical tube, considering both an open and a closed end configuration. The study utilizes a pilot flame as the ignition source. The methane (CH4) and propane (C3H8) flames were tested at equivalence ratios (ϕ) ranging from 0.9 to 1.2 a...
