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

The present study aims to construct a universal flow pattern map of immiscible liquids with Newtonian and non-Newtonian properties in a T-shaped microchannel. Immiscible liquid-liquid flow in a T-shaped rectangular microchannel with a hydraulic diameter of 267 μm was experimentally studied for liquid sets with non-Newtonian and Newtonian properties. Xanthan gum aqueous solution acted as the shear-thinning dispersed phase. The apparent viscosity of the non-Newtonian liquid varied from 23 to 1265 mPa·s. Two aqueous glycerol solutions with viscosities of 130 and 506 mPa·s were taken as reference Newtonian dispersed phases. Castor oil was a continuous phase in all experiments. High-speed visualization of the flow was performed in order to reveal flow patterns in a range of bulk velocities from 0.087 to 29 mm/s. Flow pattern maps were constructed for all liquid sets in terms of flow rates of dispersed and continuous phases. The boundaries between flow rates were shown to be shifted relative to each other in the order of magnitude. The product of the non-dimensional parameter Weber number multiplied by the Ohnesorge number was successfully utilized to distinguish segmented and continuous flow patterns for both Newtonian and non-Newtonian liquids.
