About this Research Topic

Manuscript Submission Deadline 15 November 2022

The need for a clean energy transition in the power, transportation, and industry sector poses significant scientific and technological challenges. One of the most prominent approach to the short and mid-term emission reduction is the improvement of existing combustion technologies in terms of sustainability. Combustion of low carbon fuels deems to provide the most viable option for de-carbonization to reach net zero by 2050 with a minimal impact on existing infrastructure combined with renewable energy sources. However, more efficient and safe use of such fuels in existing power, mobility and propulsion systems poses tremendous technical challenges. Therefore, it is crucial to advance combustion science and deepen the knowledge in the sustainable utilization of renewable energy carriers. This technology still faces several challenges in terms of both production/storage and usage. To achieve this goal, considerable multidisciplinary experimental, theoretical and modelling efforts are necessary to improve the understanding of the physics and chemistry of flames, paving the way for sustainable solutions in terms of greenhouse gases, pollutant emissions reduction and fuel flexible systems, aiming for a net-zero carbon balance.

The goal of this Research Topic is to present new results, findings and developments in the various disciplines associated with combustion science, pollutants formation /destruction and utilization of renewable energy carriers. The Editors invite original contributions dealing with experimental investigations of flames, novel experimental diagnostics, chemical kinetics, CFD modeling of reacting flows simulations, pollutants formation measurements and mechanisms (NOx, SOx, non-regulated pollutants, particulate matter), renewable energy carriers, hydrogen and ammonia, data-driven methods for combustion and material synthesis processes. Authors who attended the 44th ASICI Meeting 2022 – Combustion for Sustainability, held in Naples (Italy), are encouraged to contribute through the submission of a full-paper research articles and mini-review.

Original research articles and mini-reviews including, but not limited to, the following areas of interest are welcome:
• Low-Emission Combustion Technologies including low-carbon and hydrogen-based fuels, MILD combustion, oxy-fuel combustion, chemical looping, NOx and SOx reduction, and CO2 capture strategies;
• Reaction Kinetics including the kinetics of hydrocarbons, oxygenated fuels and alternative energy carriers, formation of pollutants, elementary reactions, and mechanism generation and reduction;
• Laminar and Turbulent Flames including experiments, theory, and modeling applied to ignition, propagation, extinction, stabilization, dynamics, and instabilities;
• Spray, Droplet, and Supercritical Combustion including atomization, combustion of droplets, sprays, and supercritical fluids;
• Detonation, Explosion, and Supersonic Combustion including fundamental aspects of ignition and flame acceleration, fire safety aspects, rotating- and pulse-detonation engines, constant volume combustion engines and scramjet-engines;
• Solid Fuel Combustion including fundamental aspects related to pyrolysis, oxidation, gasification, and ash formation from coal, biomass, and wastes, as well as combustion of propellants and metals;
• Propulsion and engines including device-specific aspects of fuels, emissions, injection, stability, combustion dynamics, internal combustion engines, gas turbines and rocket engines;
• Soot, Nanomaterials, and Large Molecules including the formation, growth, and destruction of soot, PAHs, carbon nanostructures, and other nanoscale materials;
• Multi-Physics Phenomena including assisted combustion (plasmas, electric and magnetic fields), catalysis, coupled heat transfer, micro-channel reactors, fuel cells, fuel synthesis and transformation, and electrolysis.

Keywords: Low Emission Technologies, Energy Carriers, Sustainable Mobility and Propulsion, Numerical Modeling, Materials and Flame Synthesis
