Special Issue Information

Dear Colleagues,

As the world continues to grapple with the challenges of climate change and environmental degradation, the search for sustainable sources of energy has become more pressing than ever before. Low-carbon fuels, such as hydrogen, ammonia, biofuels, and synthetic fuels, have emerged as promising alternatives to traditional fossil fuels. However, the efficient combustion of these fuels remains a key challenge that must be overcome in order to realize their full potential. Fundamental scientific research on combustion behaviors, such as flame spread, combustion mechanisms, and combustion modeling, will contribute to the comprehensive understanding of flame development and the realization of efficient combustion.

This Special Issue aims to bring together researchers and practitioners from across the world to share their latest findings, insights, and experiences on the efficient combustion of low-carbon fuels. We invite original research articles, review papers, and case studies that address topics such as:

  • Theoretical and experimental studies of the combustion of low-carbon fuels;
  • Novel combustion technologies for low-carbon fuels;
  • Combustion performance optimization and control for low-carbon fuels;
  • Emission reduction strategies for low-carbon fuels;
  • Environmental and economic assessments of low-carbon fuel combustion;
  • Advanced combustion systems and technologies for low-carbon fuels.

We encourage submissions from a wide range of fields, including mechanical engineering, chemical engineering, materials science, and environmental science. Our goal is to provide a comprehensive and interdisciplinary overview of the current state of knowledge on the efficient combustion of low-carbon fuels and to identify promising avenues for future research.

This Special Issue aims to examine the frontiers of low-carbon fuel combustion, including experiments and numerical simulations studies of flame behaviors, combustion mechanism, combustion modeling, combustion efficiency, and emissions characteristics.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Experimental studies on low-carbon fuels combustion;
  • Numerical simulations of combustion and applications of advanced numerical models;
  • Applied combustion physics and chemistry, including combustion kinetics thermochemical reactions, heat transfer, and ignition characteristics;
  • Flame behaviors of low-carbon fuels combustion;
  • Progress in combustion modeling;
  • Properties of combustion products;
  • Emissions control.

This study investigates the performance and environmental impact of n-butanol blended with Jet-A fuel in turbo engines, aiming to assess its viability as a sustainable aviation fuel (SAF). The research involves the experimental testing of various blends, ranging from low to high concentrations of n-butanol, to determine their effects on engine performance and emissions. The experimental setup includes comprehensive measurements of engine parameters such as thrust, fuel consumption rates, and exhaust gas temperatures. Emissions of sulfur dioxide (SO2), and carbon monoxide (CO) are also analyzed to evaluate environmental impacts. Key findings indicate that n-butanol/Jet-A blends can significantly enhance combustion efficiency and reduce emissions compared to conventional Jet-A fuel. Higher n-butanol concentrations lead to improved thermal efficiency and lower SO2 and CO emissions. This study underscores the potential of n-butanol as an SAF for turbo engines, highlighting its ability to mitigate environmental impacts while maintaining or improving engine performance. This research supports the feasibility of integrating n-butanol into Jet-A blends for turbo engine applications, emphasizing their role in achieving more environmentally friendly aviation operations.

The objective of this study was to investigate the effect of a premixed ethanol ratio based on the same total heating value in a cylinder on the equivalence ratio distributions and the injected fuel droplet behavior in the cylinder of an RCCI engine. The spray simulation was conducted in two parts. First, we carried out spray validation simulations to determine the spray-influenced factor of the test injector. Next, engine simulations were performed with the spray-influenced factor obtained from the spray validation simulations to investigate the effect of the premixed ethanol ratio based on the same total heating value in a cylinder on the injected fuel atomization and the equivalence ratio distributions. The introduced total heating value was fixed at 595 J based on the lower heating value of diesel, 14 mg. The heating value of the premixed ethanol ratio varied from 0% to 40% based on the same total heating value in the cylinder in steps of 10%. It was revealed that when the premixed ethanol ratio based on the same total heating value in the cylinder was increased, the spray tip penetration value was reduced after 4 deg of diesel was injected because of the short injection duration and the small amount of diesel fuel used. The SMD value was also increased up to 32.58% with an increasing premixed ethanol ratio because of the low kinetic energy of the injected fuel, the short injection duration, the slow evaporation of the injected fuel and the low cylinder temperature.

Transitioning to low-carbon energy systems is crucial for sustainable development, particularly in oil-rich developing countries (ORDCs) that face intertwined economic and environmental challenges. This review uses the PRISMA methodology to systematically assess the current state and prospects of low-carbon thermal electricity generation and utilization technologies in ORDCs. The study emphasizes clean thermal technologies such as biogas, biofuels, biomass, hydrogen, and geothermal energy, focusing on solutions that are technically feasible, economically viable, and efficient in combustion processes. These nations face significant challenges, including heavy reliance on fossil fuels, transmission losses, and financial constraints, making energy diversification urgent. The global shift towards renewable energy and the need to mitigate climate change presents an opportunity to adopt low-carbon solutions that align with Sustainable Development Goals related to energy access, economic growth, and climate action. This review aims to (1) evaluate the current state of low-carbon thermal electricity technologies, (2) analyze the technical and economic challenges related to combustion processes and energy efficiency, and (3) provide recommendations for research and policy initiatives to advance the transition toward sustainable thermal energy systems in ORDCs. The review highlights practical approaches for diversifying energy sources in these nations, focusing on overcoming existing barriers and supporting the implementation of clean thermal technologies.
