Analysis of Thermoacoustic Modes in Can-Annular Combustors Using Effective Bloch-Type Boundary Conditions
von Saldern, Jakob; Orchini, Alessandro; Moeck, Jonas (Peer reviewed; Journal article, 2020)Heavy-duty gas turbines are commonly designed with can-annular combustors, in which all flames are physically separated. Acoustically, however, the cans communicate via the upstream located compressor plenum, or at the ... -
A Non-Compact Effective Impedance Model for Can-To-Can Acoustic Communication: Analysis and Optimization of Damping Mechanisms
von Saldern, Jakob; Orchini, Alessandro; Moeck, Jonas (Peer reviewed; Journal article, 2021)Can-annular combustors can feature azimuthal instabilities even if the acoustic coupling between the individual cans is weak. Recently, various studies have focused on modeling the acoustic communication between adjacent ... -
Nonlinear interaction between clustered unstable thermoacoustic modes in can-annular combustors
von Saldern, Jakob; Moeck, Jonas; Orchini, Alessandro (Peer reviewed; Journal article, 2020)A can-annular combustor consists of a set of nominally identical cans, in which the flames burn in an essentially isolated manner. However, adjacent cans are able to communicate acoustically, which provides dynamic coupling ...
