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: 0.5 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: 0.8 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: 0.2 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: 0.00018 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: 0.11 SJR: 0.286 SNIP: 1.032 CiteScore™:: 1.6 H-Index: 10

SINOPSIS

A numerical and experimental study has been carried out with a pair of water drops coalescing over a superhydrophobic surface. Initially, a stationary isolated drop (of given radius R) in the sessile configuration is just touched by another drop (of radius R2), vertically in line with it, at zero speed. The solid substrate is a chemically treated, polished superhydrophobic surface made up of copper, for which the equilibrium contact angle for water was measured to be 150°. The Bond number, considering the total volume of the combined drop, falls in the range of 0.3−0.5. For these conditions, experiments clearly reveal that for a given range of R1/R2, the merged drop bounces off once before it starts to eventually spread and attain an equilibrium configuration. The above experiment has been numerically simulated using COMSOL©, in an axisymmetric coordinate system. The simulations have been carried out for different combinations of droplet volumes, while keeping their combined volume to be fixed. The predictions of the simulation are compared with the experiment in terms of the interface shapes attained, distinctive timescales, and recoil height. The comparison between the two sets of data is seen to be favorable. Factors leading to recoil are delineated according to the available energy budget.
