Abstract: Premixed flames are sensitive to flow disturbances, which can arise from acoustic or vortical fluctuations. For transverse instabilities, it is known that a dominant mechanism for flame response is “injector coupling,” ...

Abstract: Swirling jets are canonical flow fields used to stabilize flames in many gas-turbine combustion systems. These flows amplify background acoustic disturbances and perturb the flame, producing combustion noise and potentially ...

Abstract: Hydrogen (H2) fuel for gas turbines is a promising approach for long duration storage and dispatchable utilization of intermittent renewable power. A major global discussion point, however, is the potential air quality ...
