Special Issue Information

Dear Colleagues,

We invitesubmissions to the Special Issue on Clean Combustion Technologies and Renewable Fuels.

In the context of global climate change and the pressing demand for sustainable energy, clean combustion technologies and renewable fuels stand as pivotal solutions reshaping the energy landscape. This Special Issue is dedicated to highlighting advancements in emissions reduction and efficiency enhancement that foster a greener, more resilient future. Advancements in clean combustion technologies include, but are not yet limited to, low-emission engines, high-efficiency burners, and sophisticated emission control systems. Contributions are invited to illuminate novel methodologies, experimental validations, and modeling endeavors aimed at minimizing pollutants and greenhouse gas emissions. With respect to renewable fuel sources and production, we welcome contributions that scrutinize the latest research endeavors pertaining to biofuels, hydrogen, solar-thermal fuels, and other renewable energy vectors. Submissions are encouraged to address production methodologies, feedstock origins, cost–benefit analyses, and environmental impact evaluations. Contributions are welcome on the integration of renewable fuels and clean combustion systems, as well as the exploration of optimal integration strategies for renewable fuels within existing and emerging energy systems, spanning transportation, power generation, and industrial applications. Contributions should emphasize system design considerations, performance evaluations, and economic feasibility assessments. In the field of energy storage and microgrids, we welcome investigations into advanced energy storage technologies and microgrid systems that facilitate the seamless integration of renewable fuels and clean combustion technologies. Other pertinent topics include battery storage solutions, pumped hydro systems, thermal storage mechanisms, and hybrid systems.

Industrial development and population growth have significantly escalated worldwide energy demand; in addition, the heightened consumption of primary energy sources such as hydrocarbons has profoundly impacted the atmospheric environment. Among all potential fuels, hydrogen provides the most significant advantages for energy supply and environmental sustainability. Nonetheless, the combustion of pure hydrogen has challenges related to its production, storage, and utilization. A more effective approach to improve combustion is to utilize hydrogen as an addition to fossil fuels. Hydrogen possesses numerous characteristics that render it a compelling fuel alternative. It possesses high energy density, offering triple the energy compared to liquefied petroleum gas. This indicates that hydrogen is able to deliver equal power output with reduced fuel usage, thus decreasing the fuel used and, consequently, greenhouse gasses linked to combustion. In this study, practical experiments and computer simulations were adopted to predict the behavior of some characteristics of the combustion of Iraqi liquefied petroleum gas, such as flame temperature and laminar burning velocity, in addition to the effect of changing the equivalence ratio and hydrogen enrichment at rates ranging between 5 and 20% at a constant atmospheric pressure and temperature. In the practical aspect, a counter-flow burner was developed at the Training and Workshops Center, University of Technology, Iraq, for the purpose of performing practical experiments. In addition, a MATLAB R2023b program code was developed based on flame front image frames to analyze data and measure flame parameters, i.e., laminar burning velocity, flame temperature, and flame front diameter. While the commercial CFD Ansys Fluent version 17.2 program was used to numerically simulate the premixed counter-flame, the steady laminar flame (SLF) was used. Also, in order to implement the continuity of the numerical simulation, the momentum and energy equations of the counter-flow burner were solved. The results showed that increasing the hydrogen percentage caused an increase in the laminar burning velocity as well as the flame temperature; when the hydrogen percentage in the mixture was 20%, the increasing percentages in the practical experiments were about 25% and 19.6%, respectively, and the percentages in the numerical simulation were about 22.6% and 20.5%, respectively. Also, changing the equivalence ratio from 0.4 to 1.4 had an effect on the shape, color, and method of flame spread, where at the higher percentage, the shape changed and the color concentration increased, meaning that the temperature rose and the method of spread changed to an irregular one. Additionally, several recommendations are suggested for future endeavors in this domain. Full article

The current work includes experimental and numerical investigations into the effects of biodiesel (Eichhornia Crassipes) blends with different aluminum oxide nanoparticle concentrations on the combustion process in diesel engines. The experiments included measuring performance parameters and emissions tests while changing the engine speed and increasing loads. IC Engine Fluent, a specialist computational tool included in the ANSYS software (R19.0 version), was used to simulate internal combustion engine dynamics and combustion processes. All investigations were carried out using biodiesel blends with three concentrations of Al2O3 nanoparticles: 50, 100, and 150 ppm. The tested samples are called D100, D80B20, D80B20N50, D80B20N100, and D80B20N150, accordingly. The combustion characteristics are improved due to the catalytic effect and higher surface area of nano additives. The results showed improvements in the combustion process as the result of the nanoparticles’ addition, which led to the higher peak cylinder pressure. The increases in the peak cylinder pressures for D80B20N50, D80B20N100, and D80B20N150 about D80B20 were 3%, 5%, and 8%, respectively, at a load of 200 Nm, while the simulation found that the maximum temperature for biodiesel blends diesel was higher than that for pure diesel; this was due to the higher hydrocarbon values of D80B20. Also, nano additives caused a decrease in temperatures in the combustion of biofuels. Finally, nano additives caused an enhancement of the emissions test results for all parameters when compared to pure diesel fuel and biofuel. Full article
