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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

ABSTRAKT

This paper reports results of an experimental study on various fluid patterns produced by two symmetric impinging Newtonian liquid jets. Water–glycerol mixtures with viscosities of 5 mPa·s, 15 mPa·s, and 40 mPa·s were used to study the effect of viscosity on fluid patterns. Two liquid jets with a diameter of 0.76 mm each were made to impinge on each other. Images in the plane perpendicular to both liquid jets were captured using a backlight direct imaging method using a 4 MPixel CCD camera. New types of periodic patterns, which to date have not been reported for Newtonian liquids, were observed in this study. It was observed that the velocity at which periodic patterns start to appear depends on the liquid viscosity. A fish-bone-like periodic structure was observed only with the 5 mPa·s liquid, while periodic shedding of droplets from the rim is not observed with the 40 mPa·s viscosity liquid. Periodic patterns were observed for all the liquids only at an impinging angle of 60°, unlike in earlier studies where the patterns were observed with an impinging angle of 90°. It was also observed that significant asymmetry between the liquid jets is not necessary for the formation of periodic patterns.
