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

RÉSUMÉ

We have developed a three-dimensional model of free surface flows that can accommodate the presence of arbitrary-shaped obstacles in the flow. The model is an extension of one developed earlier by Bussmann, Mostaghimi, and Chandra [1]. To validate the model we simulated the impact of a 2-mm-diameter water droplet landing with low velocity (~1 m/s) on tubes ranging in diameter from 0.5 to 6.35 mm. Computer-generated images of droplet deformation after impact agreed well with photographs. Droplets landing on the largest tube (6.35-mm diameter) clung to the solid surface following impact. On smaller tubes there was not enough surface area for the liquid to remain attached, and droplets fell off after impact, disintegrating into several smaller droplets as they fell. The number of droplets produced after breakup was sensitive to the location of the impact point on the tube surface.
