Intrinsic aeroacoustic instabilities in the crosstalk apertures of can-annular combustors [PDF]

open access: yesarXiv
This paper presents an experimental and numerical study of aeroacoustic instabilities at the interface between neighbouring combustion chambers in modern heavy-duty gas turbines. A simplified laboratory-scale geometry of the gap separating the outlet of these chambers, just upstream of the turbine inlet in can-annular combustor architectures, is ...
