Special Issue Information

Dear Colleagues,

The world population will increase up to 8.7 billion people by 2035, causing an increase in the consumption of primary energy by 37 % between 2013 and 2035. Almost 20% of the annual energy consumption is used in the transportation sector and among this, 95% of energy comes from burning fossil fuels. During the last few decades, fossil fuel depletion, the global energy crisis and its environmental consequences have played a significant role in motivating research community to come up with alternative/renewable sources of energy in which biofuels are considered a promising candidate. With the ever increasing types of biofuels being made, the primary goals now are to reduce fuel consumption, enhance engine performance, and minimize the exhaust emissions.

To be compatible with the modern engines, biofuels must possess similar viscosity, density, and surface tension, which affect fuel injection process and spray quality. This impacts the fuel spray atomization and hence the fuel economy, power output efficiency of combustion and exhaust gases in direct injection engines. The spray dynamics is a complex phenomenon having a number of energy exchange processes like cavitation, turbulence, primary atomization, secondary breakup, aerodynamic drag, drop collision, coalescence and evaporation. Atomization of fuel and breakup of droplets are the most critical of all physical processes for fuel sprays, making it a major topic of interest for engine researchers.

Hence, this Special Issue aims to publish high-quality original research papers on the spray characteristics of biofuels with their impact on engine performance and emissions. Special emphasis is laid on improvements in fuel conversion efficiency, fuel injection and spray characteristics, leading to reduction in pollutant formation. This issue will also cover related areas of engine performance parameters such as, but not limited to, brake power, specific fuel consumption, specific energy consumption, and thermal efficiency of biofuels. Moreover, it will also cover analysis on exhaust emissions that may or may not be linked with the spray dynamics stated earlier.

The papers selected for this Special Issue will proceed through rigorous peer review with the aim to bridge the gap of biofuel development with its real world application. We therefore request the research community to submit their original work in form of communication, research article or review articles covering the theoretical and experimental aspects of biofuel development.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs).
