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

ABSTRAKT

Droplet atomization and evaporation in dense sprays is relevant to several physical applications. We report a population balance model wherein these processes are handled simultaneously. The model is implemented in an Eulerian-Eulerian multiphase framework wherein the drop phase is itself modeled as multiple continua. The continuum model of the drop phase allows us to incorporate a stress field which naturally arises in a collision dominated dense spray. The utility of the model is first demonstrated on a uniform flow evaporator, wherein the mean droplet surface area is shown to exhibit a similarity scaling in terms of a nondimensional parameter that characterizes the competition between atomization and evaporation. The model is then generalized to a computational fluid dynamics (CFD) situation wherein a plug flow atomizer/evaporator is studied. The continuous variation of Sauter mean diameter (SMD) in the flow is presented wherein atomization processes cause the SMD to decrease while evaporation processes cause the SMD to locally increase. This is due to the preferential disappearance of the smaller size drops. Finally, the utility of the model for studying dense droplet ensemble atomization, evaporation, and combustion is discussed.
