About this Research Topic
The escalating concerns over climate change and finite fossil fuel resources have prompted a paradigm shift towards alternative fuels in combustion processes. Alternative fuels such as H2, NH3, natural gas, biofuels, etc., are found to be versatile and capable of being produced from renewable sources. Thereby, these fuels hold great potential in decarbonizing the transport industry and abating CO2 emissions during their use. However, the combustion properties as well as the emission products of these fuels are very different from conventional fossil fuels. Hence, it is critical to study and understand the fundamental combustion characteristics and emissions of these fuels. This knowledge forms the basis for impacting meaningful change in practical applications and steering us toward an environmentally sustainable future.
The primary goal of this Research Topic is to showcase recent advancements in comprehending the ignition/combustion properties and emission products of emerging low-carbon alternative fuels such as H2, natural gas, NH3, methanol, ethanol, biofuels, etc. It provides a platform for addressing both experimental and modeling investigations of combustion, with a focus on reducing CO2 emissions from their end use. Experimental diagnostic techniques, including measuring ignition delay times, laminar flame speeds, laser diagnostics, etc., along with numerical modeling techniques like chemical kinetics modeling and kinetic mechanism reductions, can play key roles in understanding the fundamental basics of these fuels. These endeavours have the potential to significantly accelerate the development and deployment of alternative fuel engines.
This Research Topic is dedicated to advancing the fundamental understanding of alternative fuels to address the challenges in the realms of energy and emissions. Topics include but are not limited to:
• Experimental investigation of ignition and combustion properties of alternate fuels, like H2, CH4, natural gas, NH3, alcohol, DME, biofuels, etc.
• Numerical modeling & validation of chemical kinetics and/or reactive flow analysis for these fuel systems.
• Advanced combustion technologies like catalytically assisted combustion.
• Novel fuel systems such as hydrogen assisted methane/natural gas combustion.
• Emission products from these fuels and their abatement.
We welcome Original Research, Review, Mini Review and Perspective articles.
