The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00095 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

RESUMO

An evaporation model for realistic multicomponent fuels is described. In the model a new approach, named the discrete/continuous multicomponent (DCMC) model, is used to describe the properties and composition of realistic multicomponent gasoline fuels. With this approach gasoline is assumed to consist of five discrete families of hydrocarbons: n-paraffins, i-paraffins, naphthenes, aromatics, and olefins. Each family of hydrocarbons is composed of an infinite number of continuous components, which are modeled as a probability density function (PDF), and the mass fraction of each family of hydrocarbons is represented by a PDF, and the mean and variance of each PDF are tracked. Compared with the discrete multicomponent model, which must model hundreds of components for gasoline, the DCMC model saves computer time. Compared with the continuous multicomponent model, the DCMC model has much higher accuracy. Unsteady evaporation of multicomponent fuel can be described for both normal and flash-boiling evaporation conditions. An unsteady internal heat flux model and a model for the determination of the droplet surface temperature were formulated. An approximate solution to the quasi-steady energy equation was used to derive an explicit expression for the heat flux from the surrounding gas to the droplet-gas interface, with interdiffusion of fuel vapor and the surrounding gas taken into account. The present DCMC evaporation model was implemented into a multidimensional computational fluid dynamics code and applied to calculate the evaporation processes of single- and multicomponent fuel droplets.
