Special Issue Information

Dear Colleagues,

Combustion has been the key technology that enabled unprecedented development in the last century. As an example of the evolution during this period, at the beginning of the 1900s, vehicles with internal combustion engines and electric powertrains were on a par; due to several advantages, gasoline-powered units became the dominant power source for mobility, while the latter featured a marginal presence. Recently, the electric motor has been receiving renewed interest, mainly due to significant progress in battery technology, and appears to be the choice of most decision-makers for the future of mobility. When comparing the two aforementioned solutions, there are several unresolved issues such as the debate with respect to well-to-wheel ratings or the significant role of combustion in generating the energy that actually drives electric vehicles. Nonetheless, there is an important social and political drive towards electrification of mobility. This of course has a range of consequences on the energy generation sector and eventually on the future development of combustion-based conversion technologies.

As a consequence, the current Special Issue plans to investigate the most recent advances in combustion processes and how these developments fit within the current energy and mobility scenario. Papers that cover all combustion-related processes are welcome, ranging from basic studies of non- and premixed flames, to thermodynamic processes connected with thermal energy conversion, including active as well as passive methods for emissions control. The unifying theme is the scrutiny of advances within the current situation and foreseen scenarios, and thus interactions with other forms of energy conversion are also of significant interest, including hybrid powertrains.

Research in the process of internal combustion engines shows that their efficiency can be increased through several technical and functional solutions. One of these is turbocharging. For certain engine operating modes, the available energy of the turbine can also be used to drive an electricity generator. The purpose of this paper is to highlight the possibilities and limitations of this solution. For this purpose, several investigations were carried out in the virtual environment with the AMESim program, as well as experimental research on a diesel engine for automobiles and on a stand for testing turbochargers (Turbo Test Pro produced by CIMAT). The article also includes a comparative study between the power and torque of the naturally aspirated internal combustion engine and equipped with a hybrid turbocharger. The results showed that the turbocharger has a very high operating potential and can be coupled with a generator without decreasing the efficiency of the turbocharger or the internal combustion engine. The main result was the generation of electrical power of 115 W at a turbocharger shaft speed of 140,000–160,000 rpm with an electric generator shaft speed of 14,000–16,000 rpm. There are many constructive solutions for electrical turbochargers with the generator positioned between the compressor and the turbine wheel. This paper is presenting a solution of a hybrid turbocharger with the generator positioned and coupled with the compressor wheel on the exterior side. Full article

The dynamics of the particle size distribution (PSD) of polydispersed fuel spray is important in the evaluation of the combustion process. A better understanding of the dynamics can provide a tool for selecting a PSD that will more effectively meet the needs of the system. In this paper, we present an efficient and elegant method for evaluating the dynamics of the PSD. New insights into the behaviour of polydispersed fuel spray were obtained. A simplified theoretical model was applied to the experimental data and a known approximation of the polydispersed fuel spray. This model can be applied to any distribution, not necessarily an experimental distribution or approximation, and involves a time-dependent function of the PSD. Such simplified models are particularly helpful in qualitatively understanding the effects of various sub-processes. Our main results show that during the self-ignition process, the radii of the droplets decreased as expected, and the number of smaller droplets increased in inverse proportion to the radius. An important novel result (visualised by graphs) demonstrates that the mean radius of the droplets initially increases for a relatively short period of time, which is followed by the expected decrease. Our modified algorithm is superior to the well-known ‘parcel’ approach because it is much more compact; it permits analytical study because the right-hand sides of the mathematical model are smooth, and thus eliminates the need for a numerical algorithm to transition from one parcel to another. Moreover, the method can provide droplet radii resolution dynamics because it can use step functions that accurately describe the evolution of the radii of the droplets. The method explained herein can be applied to any approximation of the PSD, and involves a comparatively negligible computation time. Full article
