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

The present study extends the previous droplet models [1,2] to investigate numerically the system of three droplets that are moving in tandem with respect to the free flow. The purposes of this study are to study the wake effect of the lead droplet on the downstream droplets and to examine the effects of initial spacing on the total system. The effects of variable thermophysical properties, transient heating and internal circulation of liquid, deceleration of the flow due to the drag of the droplet, boundary-layer blowing, and moving interface due to surface regression, as well as relative droplet motion, are included. The results are compared with those of an isolated droplet [1] as well as those of the two-droplet system [2] to investigate the effect of the presence of the third droplet. The interaction effects from the downstream or upstream droplet are identified. The transport rates of droplets are reduced from the values for an isolated droplet, and values for the downstream droplets are profoundly less Лап those for the lead droplet. The difference in transport rates is large between the first two droplets; however, it becomes insignificant between the second and the third droplets. The modifications to the transfer correlations for an isolated droplet needed to account for the interaction effects are determined.
