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: 2.3 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: 1.8 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: 0.00037 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: 0.6 SJR: 0.433 SNIP: 0.593 CiteScore™:: 4.3 H-Index: 35

Краткое описание

The purpose of this study is to present highly accurate, comprehensive in-tube evaporation data on several commercially available internally enhanced tubes. Data is presented for the two most popular sizes for use by designers of high-efficiency heat-exchange equipment. The experiments were performed over a wide heat-flux range to ensure that the data were applicable for many uses.
In support of this purpose, seven copper tubes were tested with pure HCFC-22 in a water to refrigerant counter-flow heat exchanger to determine their in-tube boiling characteristics and pressure drops at approximately ARI (Air-Conditioning and Refrigeration Institute, Arlington, Virginia, U.S.A.) conditions. Three 9.53 mm (0.375 inch) outside diameter tubes were tested: one with 60 internal ridges and a helix angle of 18°, one with 72 straight internal ridges (no helix), and one with a smooth internal surface. Four 15.88 mm (0.625 inch) outside diameter tubes were tested: one with 60 internal ridges, one with 75 internal ridges, one corrugated, and one with a smooth internal surface.
A typical rifled tube profile is shown in the micrograph of Figure 1. It consists of equally spaced fins that are typically characterized by their height, base width, and shape. Heat exchanger designers specify these tubes by outside diameter, ridge height, number of fins, helix angle, and bottom wall thickness, as defined in Figure 2. The dimensions of the 9.53 mm tubes are listed in Table 1. The dimensions of the 15.88 mm tubes are listed in Table 2.
The results indicated that the 9.53 mm tube with 60 ridges and an 18° helix angle and the 15.88 mm tube with 75 internal ridges and a 23° helix angle angle, (Turbo-A® and 75 ridge Turbo-DX® as manufactured by Wolverine Tube, Inc.), give the highest heat transfer enhancements for the respective tube sizes considered in this test program.
