RISNumerical Analysis of Equivalence Ratio Fluctuations in a Partially Premixed Gas Turbine Combustor Using Large Eddy Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present work, the fluctuations of equivalence ratio in the PRECCINSTA combustor are investigated via large eddy simulations (LES). Four isothermal flow cases with different combinations of global equivalence ratios ...
On the Optimum Distribution of Multiple Helmholtz Resonators for Annular Combustors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The combustors of many modern land-based gas turbines and aero-engines are annular. This kind of combustors often suffer from thermoacoustic oscillations, with the occurrence of mostly the circumferential first-order, ...
