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

ABSTRACT

A steady, one-dimensional, low-speed flame propagating in a dilute, monodisperse, sufficiently off-stoichiometric and weakly heterogeneous spray with external heat recirculation, is analyzed using activation energy asymptotics. A prevaporized mode and a partially prevaporized mode of flame propagation are identified. Heat recirculation is achieved by transferring heat through a tube wall within a given distance L. The external heat transfer results in globally external heat loss and excess enthalpy burning (which is globally adiabatic), respectively, to the spray system with increasing wall temperature. The influences of external heat recirculation and liquid fuel spray on the flammability limit and extinction of spray flames are examined with three parameters, namely, the amount of external heat transfer, the liquid fuel loading, and the initial droplet size. It is found that the extent of flammability is enlarged with increasing liquid loading or decreasing droplet size for lean sprays, while the opposite holds for rich sprays; and that the change of an extinction curve to a curve characterized by blow-off and flashback is controlled by the balance between internal and external heat transfer.
