Special Issue "Influence of Biofuel Additions on the Ignition Delay of Single Diesel Fuel Drops"
Deadline for manuscript submissions: closed (30 June 2021).
Interests: microalgal biofuels for transport; energy and transport policy; interactions between scientific development, technological change, and private sector activities in the renewable energy sector
Until recently, it had not been recognized that diesel fuel blends with biofuels offer advantages for public transportation, hybrid or marine propulsion, agricultural and forestry machinery, industrial furnaces, boilers, etc. However, the nature of the fuel itself has a great influence on combustion-generated emissions. Accordingly, significant steps must be taken to control the components and the contaminants of fuel to minimize problems from emissions.
It is known that most conventional and alternative liquid fuels as well as their binary, ternary or multicomponent blends that are used for energetic means, especially these days, however, are mixtures of many chemical compounds with widely different volatilities. A detailed understanding of droplet ignition, droplet cluster ignition, and combustion are of interest in view of a detailed understanding of the ongoing basic physical and chemical processes. This kind of research is motivated by both (i) safety considerations in various systems, in which the ignition must be avoided (explosions in industrial installations, fire safety in space environments, and prevention of autoignition in the fuel delivery systems) and (ii) a pressing need for parametric studies to compile libraries of droplet ignition and combustion data as an essential prerequisite for any understanding of spray combustion and its application to the design of efficient combustion systems.
Combustion of a biofuel–diesel single droplets in an oxidizing atmosphere has been a subject of investigation over the past three decades after a few countries in Europe began to take an interest in biofuels in the early 1990s. While many reviews and original research articles have appeared on various aspects of droplet ignition, there are many important features which have yet to be explained. The present issue constitutes a reexamination of the problem of liquid biofuel–diesel droplet combustion and will therefore discuss experimental, theoretical, and computational research dealing with droplet ignition delay phenomena.
Examples of such cases include but are not limited to:
- The droplet ignition in a high-pressure environment;
- Ignition of bi-component and multicomponent droplets of oxygenated diesel fuel;
- The effects of 1st–4th-generation biofuel additives on ignition delay of diesel fuel droplets;
- The application of droplet theories with a special emphasis on ignition delay to the modeling of various combustion systems;
- Determination of ignition characteristics of the droplets containing biological additives that are not yet commercialized and could potentially be produced from hundreds of different industrial and non-industrial species, like algal biomass;
- Quasi-steady and unsteady models for the ignition of a fuel droplet in a stagnant environment;
- Convective effects on droplet ignition.
