TL;DR: In this article, the authors reviewed the occurrence of the precessing vortex core (PVC) and other instabilities, which occur in, swirl combustion systems whilst identifying mechanisms, which allow coupling between the acoustics, combustion and swirling flow dynamics to occur.

TL;DR: In this article, the definition and benefits of combined cooling, heating and power (CCHP) systems are clarified; then the characteristics of CCHP technologies, especially technical performances, are presented, as well as the status of utilization and developments.

TL;DR: In this article, the effect of finite thermal conductivity and recirculation in droplets can be taken into account using the so-called parabolic model, which is a reasonable compromise between accuracy and CPU efficiency.

TL;DR: For modeling the combustion of aviation fuels, consisting of very complex hydrocarbon mixtures, it is often necessary to use less complex surrogate mixtures as mentioned in this paper, and the various surrogates used to represent kerosene and the available kinetic data for the ignition, oxidation, and combustion of KCSs are reviewed.

TL;DR: In this paper, two critical steps towards soot production in combustors are the decomposition of the fuel and the subsequent formation of aromatic hydrocarbons with one to three benzenoid rings.

TL;DR: In this article, the authors present the achievements gained in solid-sorption refrigeration prototypes since the end of the l970s, when interest in sorption systems was renewed.

TL;DR: In this article, a survey of the literature concerning the application of the second-law of thermodynamics to internal combustion engines is presented, with a detailed reference to the findings of various researchers in the field over the last 40 years.

TL;DR: In this paper, a comparison of state-of-the-art and advanced electricity and hydrogen production technologies with CO2 capture using coal and natural gas is performed, inspired by the large number of studies, of which the results can in fact not be compared due to specific assumptions made.

TL;DR: An assessment of the mechanisms and kinetics of pyrite transformation in inert and oxygen-containing atmospheres at elevated temperatures has been performed based on a literature review in this paper.

TL;DR: The formation of smoke from a burning cigarette depends on a series of mechanisms, including generation of products by pyrolysis and combustion, aerosol formation, and physical mass transfer and filtration processes as mentioned in this paper.

TL;DR: A literature review of the direct sulfation reaction is presented in this article, where the authors discuss the influence of the reaction conditions (gas concentrations, temperature and system pressure), limestone properties and additives to the reaction kinetics, the reaction mechanism and modeling.

TL;DR: In this paper, a review of the available literature results concerning the effects of turbulence on the transport (heat and mass transfer) rates from a droplet is presented, emphasizing recent findings related specifically to physical models and correlations for predicting turbulence effects on the vaporization rate.

TL;DR: In this article, the influence of modifying a jet's exit flow pattern on both the near and far-field turbulent mixing processes and on the resulting combustion performance is explored, revealing that increasing the coherence of large-scale motions can decrease molecular mixing rates, and yet can still be beneficial in some applications.

TL;DR: Macroscopic models for fluid dynamics of circulating fluidized bed (CFB) units are presented, with emphasize on applications for conditions relevant to industrial units such as fluidized-bed combustors.

TL;DR: In this article, the authors give an overview in the realm of numerical computations of polydispersed turbulent two-phase flows, using a mean-field/PDF approach, where the mean fluid properties are computed by solving RANS equations with a classical finite volume procedure whereas the local instantaneous properties of the particles are determined by solving stochastic differential equations (SDEs).
