RISAn Optimized and Reduced Chemical Kinetic Model for Hydrogen and Natural Gas Blends Combustion in Industrial Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Natural gas is one of the common fuels that is used in gas turbines for power generation. Due to its interest in power generation and other applications, there are several chemical kinetic models available in the literature ...
Experimental Ignition Delay Time Measurements and Chemical Kinetics Modeling of Hydrogen/Ammonia/Natural Gas Fuels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, hydrogen-carrying compounds have accrued interest as an alternative to traditional fossil fuels due to their function as zero-emission fuels. As such, there is interest in investigating hydrogen-carrying ...
Extended Testing of the Auto-Ignition Characteristics of Hydrogen–Natural Gas Mixtures for the Safety of Power Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A successful transition to global clean energy hinges on meeting the world’s growing demand for power, while at the same time reducing greenhouse gas emissions. Achieving this will require significant growth in electricity ...
Investigation of NOx and Ammonia Slip in an Ammonia- and Hydrogen-Powered Aviation Gas Turbine Using Chemical Reactor Network Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Ammonia is a promising green fuel with several favorable attributes that could make it a replacement for current nonrenewable aviation fuels. The feasibility of using an NH3–H2 blend as the fuel in terms of the ...
Laminar Burning Speed Measurements of Dimethyl Ether–Hydrocarbon Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Fossil fuels, when burned in the air, release large amounts of carbon dioxide (CO2) and greenhouse gases into the air, causing significant pollution. To reduce greenhouse gas emissions (CO2, CO, and NOx), alternative ...
Auto-Ignition Delay Times for Reformate Gas Mixtures From Methane Gas Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Methane slip is a prominent issue in natural gas reciprocating engines that are used in transportation and marine applications. The incomplete combustion that results in methane slip can be resolved with the ...
Influence of Equation-of-States on Supercritical CO2 Combustion Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fossil fuel based direct-fired supercritical CO2 (sCO2) cycles are gaining the attention of industry, academia, and government due to their remarkable efficiency and carbon capture at high-source temperatures. Modeling ...
Development of Detailed and Reduced Chemical Kinetic Models for Ammonia Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The power generation sector has been recently moving toward decarbonization, and there is an increased interest in replacing conventional fossil fuels with fuels that produce reduced/zero carbon emissions. One such fuel ...
Ignition Delay Times and Chemical Kinetic Model Validation for Hydrogen and Ammonia Blending With Natural Gas at Gas Turbine Relevant Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ignition delay times from undiluted mixtures of natural gas (NG)/H2/Air and NG/NH3/Air were measured using a high-pressure shock tube at the University of Central Florida. The combustion temperatures were experimentally ...
Flame Speed Measurements of Ammonia–Hydrogen Mixtures for Gas-Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent findings from the U.S. Energy Information Administration project an increase in domestic fossil fuel consumption (e.g., petroleum and natural gas) and global greenhouse gas emissions through 2050 (Nalley, S., 2021, ...
