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 model of convective droplet evaporation dynamics is presented for droplet-array configurations that feature close spacing. Comparisons with available experimental data on single and multiple ethanol droplet streams show good agreement. Evidence is presented that evaporative cooling of ethanol micro droplets is not negligible at room temperature. It is shown that local vapor accumulation in the wake of the leading droplets plays an important role in depressing the evaporation rates of the trailing droplets. The influence of ambient blowing in a direction perpendicular to the path of droplet propagation is shown to be important for the trailing droplets in situations where the evaporative flux and the cross-stream convective flux carrying the fuel vapor away are of comparable magnitude. Model predictions for a densely arranged, ordered spray system at elevated temperature and pressure suggest that in most cases the droplets approach one another, and there exist substantial differences in evaporation characteristics between the core and the periphery of the spray. Initial droplet spacings of the order of a few droplet diameters are found to cause vapor spatial distributions which suggest that if ignition occurred, droplets would burn in groups more likely.
