Special Issue Information

Dear Colleagues,

Nowadays, most human activities from stationary applications (power generation, construction and industrial production, domestic heating and cooking) to transport (automotive, railway, marine and aviation) systems are reliant on conventional fuels. Hence, there is an increasing demand for fuels worldwide, which exceeds the available reserves of the depleting fossil fuels. However, the consumption of fossil fuels causes significant damage to global and regional environments, due to emission of harmful greenhouse gases. The urgent need to protect the environment from greenhouse gas emissions while maintaining energy security requires rapid responses to develop new technologies. Challenges associated with conventional energy resources have stimulated interests in renewable energy resources such as biofuel. For instance, there have been clear gaps and rushed thoughts about replacing fossil-fuel driven engines with electric-driven ones; however, these ideas have been initiated without long-term plans for such system energy resources and recycling approaches. Biodiesels and their fossil-fuel blends have now become essential bridges to the next level of renewable energy resources. It is therefore not surprising that much research continues to be done on biodiesel fuels and processes associated with their combustion. Hence, this Special Issue is motivated by the desire to collate relevant findings and solutions.

Original research findings on biodiesels for combustion will be reviewed and organised with the aim to inform a broad range of beneficiaries of the recent developments, and to provide critical analysis of the current state-of-art biodiesel fuel technologies. All articles featured in this issue will be free to view to maximise the readability and benefits to public.

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.

The effect of three kinds of fuels used to supply a diesel engine on its characteristics, fuel consumption, and emissions was studied. The fuels comprised pure diesel, a blend of diesel with 6% of methyl ester of yellow grease in the form of rapeseed oil, and a blend of diesel with methyl ester of brown grease in the form of goose fat. The chromatographic analysis was conducted for these fuels, and the results are presented. Two tests, comprising measurement of fuel consumption and engine emissions, were conducted on a vehicle with a diesel engine operating under zero load and under full load. The engine’s characteristics, including both power and torque versus speed, were determined under full engine load. The results of these tests are presented in this paper. The results indicated that the use of different methyl ester-based biodiesel blends with the same content of diesel to supply the diesel engine resulted in different fuel consumption and emissions of the engine not only in comparison to the supply of pure diesel but between biodiesels analyzed.

The previously developed approaches for fuel droplet heating and evaporation processes, mainly using the Discrete Multi Component Model (DMCM), are investigated for the aerodynamic combustion simulation. The models have been recently improved and generalised for a broad range of bio-fossil fuel blends so that the application areas are broadened with an increased accuracy. The main distinctive features of these models are that they consider the impacts of species’ thermal conductivities and diffusivities within the droplets in order to account for the temperature gradient, transient diffusion of species and recirculation. A formulation of fuel surrogates is made using the recently introduced model, referred to as “Complex Fuel Surrogate Model (CFSM)”, and analysing their heating, evaporation and combustion characteristics. The CFSM is aimed to reduce the full composition of fuel to a much smaller number of components based on their mass fractions, and to formulate fuel surrogates. Such an approach has provided a proof of concept with the implementation of the developed model into a commercial CFD code ANSYS Fluent. A case study is made for the CFD modelling of a gas turbine engine using a kerosene fuel surrogate, which is the first of its kind. The surrogate is proposed using the CFSM, with the aim to reduce the computational time and improve the simulation accuracy of the CFD model. Full article
