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

要約

This article is the first in a two-part study on two-phase flow of R245fa in a promising, new compact plate heat exchanger (PHE) design. Two extremely thin corrugated stainless steel plates (0.15 mm thick) having a pressing depth of only 1 mm and a chevron angle of 65° were assembled together to make a single-pass refrigerant flow passage, electrically heated PHE prototype for the tests. This test section was then used to investigate its mean and local thermal-hydraulic performance. In Part I, upward single-phase and two-phase adiabatic experiments were carried out to investigate total frictional pressure drops over the PHE, while in Part II the heat transfer characteristics were studied. Besides the traditional approach of measuring pressure drops with a differential transducer, a thermal (infrared) camera was used to measure the local plate surface temperatures during the two-phase adiabatic tests and thus the corresponding local pressures were indirectly obtained within the PHE. Measurements were made over a range of saturation temperatures (19 to 35°C), mass fluxes (10 to 40 kg m−2 s−1), and vapor qualities (0.05 to 0.8) to consider their influences on two-phase pressure drop within the PHE. Several of the most widely used prediction methods in the PHE literature were evaluated with respect to the present experimental databases. Then, a new prediction method was proposed capturing all the data in a range of ±30% with 11.4% MAE.
