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

Краткое описание

The structure of gas-liquid, two-phase flow is studied by means of a time-averaged tomographic technique, which provides a representation of the local flow structure on a given cross section. Single-fiber optical probes, sensitive to the refractive index of the surrounding medium, were used to measure the local void fraction distribution, which corresponds to the time-averaged gas concentration. The spatial resolution was enhanced by bi-harmonic spline interpolation of the experimental data; the flow structure in a generic position between two reference cross sections was obtained by linear interpolation. The proposed measurement technique was applied to the investigation of an air-water intermittent flow in horizontal pipes of large diameters (0.06 and 0.08 m i.d.). The water mass flow rate was 3 kg/s, while the gas fraction of volume flow ranged from 20% to 85%. Test sections with a constant diameter and with a sharp-edged abrupt area contraction were used.
