Large Eddy Simulations of gaseous flames in gas turbine combustion chambers (2012, background): “captured with a single sector hypothesis: for example to simulate flame propagation from a burner to the next after ignition of a flame kernel [307], neighboring flames that interact with each other or the existence of an azimuthal thermo-acoustic instabilities [356].”
Acoustic and Large Eddy Simulation studies of azimuthal modes in annular combustion chambers (2012, methodology): “No forcing is added: the LES captures (if present) the oscillation modes of the combustor without any external excitation [22].”
Large-Eddy Simulation and experimental study of cycle-to-cycle variations of stable and unstable operating points in a spark ignition engine (2012, methodology): “Furthermore, this combustion model has been successfully used in piston engine [10] as well as gas turbines [34, 35, 36, 37] applications.”
Modal dynamics of self-excited azimuthal instabilities in an annular combustion chamber (2013, methodology): “[28] performed a LES of a full annular geometry with realistic burners which resulted in self-excited azimuthal spinning modes and demonstrated that the thermo-acoustic response of each burner was the same, i.”
Investigation of azimuthal staging concepts in annular gas turbines (2011, methodology): “These experimental findings have recently been reproduced by means of Large Eddy Simulation [8] or by using thermoacoustic network calculations [6, 9, 10].”
