DOI: 10.1016/j.combustflame.2019.02.008
Abstract: Abstract Low-frequency combustion instabilities arise in an aero-engine gas turbine combustor under idle/sub-idle conditions, particularly when pilot-mode non-premixed combustion is sustained. Despite the fundamental importance of such instabilities, little is known about how they are… read more here.
