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: 1.7 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: 1.4 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: 0.00072 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: 0.43 SJR: 0.318 SNIP: 0.568 CiteScore™:: 3.5 H-Index: 28

RÉSUMÉ

An experimental study was carried out to investigate the thermal characteristics of an eccentric annular wickless heat pipe (EAWHP) with deionized water as a working fluid. The eccentric annular wickless heat pipe was sealed by a high vacuum valve which is capable of changing the filling ratio. The experiments were performed in the range of 343.15–373.15 K operating temperature and 15–60% filling ratio under natural convection and forced convection. The temperature stability, uniformity, and distribution of the evaporator wall outer surface and the condenser wall inner surface of the eccentric annular wickless heat pipe are affected by various factors, such as the filling ratio, the mounting location of the heater controller sensor, and the cooling ability of the condenser section. The results show that the larger filling ratio, lower operating temperature, and the upper temperature control point have been found to be very helpful for optimizing the temperature stability and uniformity in the condenser wall inner surface under our experimental conditions. The temperature stability of the central of condenser wall inner surface can reach 0.048 K for 2 h, while the accuracy of the device for controlling temperature lies within ±2.0 K. The condenser wall inner surface temperature uniformity can be reached at 0.142 K, while that of the evaporator wall outer surface is 2.676 K. Analysis of the evaporator wall outer surface temperature distributions using a method of thermal resistance network is also presented. The ability to maintain constant evaporator temperature makes the eccentric annular wickless heat pipes effective devices for use in temperature calibration field.
