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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

要約

The paper presents a comprehensive experimental study on emulsion (oil-inwater) fluid flow through curved diffusers. The experimental setup was designed and constructed in the fluid mechanics laboratory of the faculty of engineering, Menoufiya University to perform the measurements which have been carried out on five models of curved diffusers. The measurements of pressure distributions along the outer and inner walls of the curved diffuser were performed for different area ratios, different curvature ratios (ratio of centerline arc radius to inlet width), different inflow Reynolds numbers and different emulsion holdup (ratio of oil volume to emulsion volume), while the oil concentration was varied from 0 to 20 % by volume. The experimental work was carried out using two sets of oil-in-water emulsions; the first is stabilized oil-in-water (o/w) emulsion using Sodium Dodecyl Sulfate (SDS) emulsifier and the second is unstable o/w emulsion at different holdup values. The energy-loss coefficients for each model are based on detailed measurements of the wall pressure distributions along walls of the curved-diffuser models including long upstream and downstream tangents. The energy-loss coefficient data were plotted as a function of Reynolds number for the tested models at different concentrations. New results on energy-loss coefficient during flow of destabilized and stabilized oil-in-water emulsions through curved diffusers are reported in the present paper. The diffuser energy-loss coefficient is strongly affected by the geometrical parameters of diffuser, Reynolds number and emulsion holdup. Generally for the flow in curved diffusers, the resistance coefficients for stable and unstable (oil-in-water) emulsions were higher than that of pure-water flow. It is also noticed that the unstable o/w emulsion exhibits lower values in loss coefficient compared with that given for stable o/w emulsion. General correlation of the loss coefficient (not previously considered) for the present cases exploring the ranges of geometrical parameters, inflow condition and Reynolds number conditions is extracted from the present experimental study.
