RISDesign and Numerical Investigation of a Swirl-Stabilized Hydrogen Burner for Aero Engine Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. In recent years, the potential of hydrogen as an alternative fuel for the decarbonization of the aeronautical sector has been widely recognized in both scientific and industrial combustion communities. Due to its ...
Heat Transfer Coefficient and Adiabatic Effectiveness Measurements on a Nozzle Guide Vane With a Single Row of Cylindrical Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film-cooling injection significantly affects the thermal behavior of turbine vane surfaces. In addition to the beneficial effect of the film shielding the vane from the hot gas flow, alteration of the thermal boundary layer ...
Prediction of the Flame Characteristics of an Industrial Gas Turbine Operated With CO2-Diluted Air Through a High-Fidelity Numerical Analysis: A Comparison Between Flamelet Generated Manifolds and Artificially Thickened Flame
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In light of the global commitment to decarbonize industrial processes, carbon capture and storage (CCS) plays a pivotal role in mitigating greenhouse gas emissions from gas turbine (GT) power generation processes. Achieving ...
Impact of Fuel Injection System on the Performance of an Industrial Burner With Hydrogen Piloting Operated With Simulated Exhaust Gas Recirculation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Exhaust gas recirculation (EGR) can be exploited to increase the CO2 content at the exhaust of gas turbines (GTs), in order to improve the efficiency of carbon capture systems. The lower oxygen level leads to ...
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 ...
High-Fidelity Simulation for the Lean Blow-Out Analysis of an Industrial Burner Operated With Artificial Exhaust Gas Recirculation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. In this paper an enhanced thickened flame model (TFM) capable of accounting for both premixed and nonpremixed combustion regimes is leveraged to reproduce the extinction limit of an industrial burner operating ...
Combustion Diagnostics and Emissions Measurements of a Novel Low NOx Burner for Industrial Gas Turbine Operated With CO2 Diluted Methane/Air Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: While the employment of Exhaust Gas Recirculation (EGR) is a well-established technique in Internal Combustion Engines to limit NOx emissions, its adoption in Gas Turbine engines has not yet found a practical application ...
