RISRelative Effects of Velocity- and Mixture-Coupling in a Thermoacoustically Unstable, Partially Premixed Flame
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Combustion instability, which is the result of a coupling between combustor acoustic modes and unsteady flame heat release rate, is a severely limiting factor in the operability and performance of modern gas turbine engines. ...
Impact of Hydrogen Addition on the Thermoacoustic Instability and Precessing Vortex Core Dynamics in a CH4/H2/Air Technically Premixed Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We study the impact of H2 enrichment on the unsteady flow dynamics and thermoacoustic instability in the prediction and control of instabilities in industrial turbines (PRECCINSTA) swirl combustor. The experiments were ...
Erratum: “Dynamical Characterization of Thermoacoustic Oscillations in a Hydrogen-Enriched Partially Premixed Swirl-Stabilized Methane/Air Combustor” [ASME J. Eng. Gas Turbines Power, 143(12), p. 121022; DOI: 10.1115/1.4052091]
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The following are the changes made to the original paper:1. Section 2 (Experimental setup) Last paragraph third sentence -For each combination of thermal load and equivalence ratio, the fraction of hydrogen in the fuel was ...
Dynamical Characterization of Thermoacoustic Oscillations in a Hydrogen-Enriched Partially Premixed Swirl-Stabilized Methane/Air Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, we systematically analyze the effects of hydrogen enrichment in the well-known PRECCINSTA burner, a partially premixed swirl-stabilized methane/air combustor. Keeping the equivalence ratio and thermal power ...
