Auto-Ignition of Gas Turbine Lubricating Oils in a Shock Tube Using Spray Injection

Source: Journal of Engineering for Gas Turbines and Power:;2021:;volume( 143 ):;issue: 005:;page 051008-1

Author(s): Cooper, Sean P.; Browne, Zachary K.; Alturaifi, Sulaiman A.; Mathieu, Olivier; Petersen, Eric L.

Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: In choosing the lubricating oil for a gas turbine system, properties such as viscosity, viscosity index, corrosion prevention, and thermal stability are chosen to optimize turbine longevity and efficiency. Another property ...

The Effect of Mixture Variation and Initial Temperature on the NH2* Thickness of Spherically Propagating Laminar Ammonia Flames

Source: Journal of Engineering for Gas Turbines and Power:;2024:;volume( 146 ):;issue: 012:;page 121006-1

Author(s): Almarzooq, Yousef M.; Hay, Matthew; Khan-Ghauri, Maryam; Mathieu, Olivier; Kulatilaka, Waruna D.; Petersen, Eric L.

Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: Interest in ammonia (NH3) in combustion has increased in recent years as a carbon-free fuel alternative. Therefore, understanding its combustion characteristics is crucial. One way to increase the knowledge of ammonia ...

Numerical Study on the Effect of Real Syngas Compositions on Ignition Delay Times and Laminar Flame Speeds at Gas Turbine Conditions

Source: Journal of Engineering for Gas Turbines and Power:;2014:;volume( 136 ):;issue: 001:;page 11502

Author(s): Mathieu, Olivier; Petersen, Eric L.; Heufer, Alexander; Donohoe, Nicola; Metcalfe, Wayne; Curran, Henry J.; Gأ¼the, Felix; Bourque, Gilles

Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: Depending on the feedstock and the production method, the composition of syngas can include (in addition to H2 and CO) small hydrocarbons, diluents (CO2, water, and N2), and impurities (H2S, NH3, NOx, etc.). Despite this ...

CH Kinetics Measurements and Their Importance for Modeling Prompt NOx Formation in Gas Turbines

Source: Journal of Engineering for Gas Turbines and Power:;2020:;volume( 142 ):;issue: 004

Author(s): Cooper, Sean P.; Mulvihill, Clayton R.; Mathieu, Olivier; Petersen, Eric L.; Crofton, Mark W.; Lam, King Y.

Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: Recent work by the authors and others has uncovered the need for further chemical kinetic-related modeling and experiments, specifically for NOx kinetics at engine conditions. In particular, data on CH formation at realistic ...

Laminar Flame Speed and Ignition Delay Time Data for the Kinetic Modeling of Hydrogen and Syngas Fuel Blends

Source: Journal of Engineering for Gas Turbines and Power:;2013:;volume( 135 ):;issue: 002:;page 21503
