RISCO Emission Modeling in a Heavy Duty Annular Combustor Operating With Natural Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes the development of a large-eddy simulation (LES)-based approach for the prediction of CO emission in an industrial gas turbine combustor. Since the operating point of the modern combustors is really ...
A Novel Large-Eddy Simulation-Based Process for NOx Emission Assessment in a Premixed Swirl Stabilized Combustion System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new computational fluid dynamics (CFD) approach for the assessment of NOx emission. The methodology is validated against the experimental data of a heavy-duty gas turbine annular combustor. Since the ...
Thickened Flame Model Extension for Dual Gas Turbine Combustion: Validation Against Single Cup Atmospheric Test
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of predictive combustion models is more and more strategic in the design definition of gas turbine (GT) combustor. The thickened flame model (TFM), despite its high computational cost, is one of the most ...
Numerical Modeling of Swirl Stabilized Lean-Premixed H2–CH4 Flames With the Artificially Thickened Flame Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The lean premixed technology is a very convenient combustion strategy to progressively move from natural gas to high hydrogen content fuels in gas turbines limiting the pollutants emissions at the same time. The enabling ...
