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: 1.2 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: 0.3 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: 0.00095 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: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

要約

Thermal management issues necessitate the use of fuel as a heat sink for gas turbine and liquid rocket engines. As interest in heated fuels increases, it is important to understand what occurs in the flow path of an injector under flashing conditions. This article describes a flow visualization study to characterize the flow of flashing methanol through two high aspect ratio slot orifice injectors of differing sizes. Flashing conditions inside the injector flow path were induced via a combination of heating and back pressure adjustments. Volume flow rate, pressure measurements, and temperature measurements were made that allowed the discharge characteristics, the level of super heat, and other parameters to be calculated and compared. To give a basis for comparison, the flashing results are compared to the flow through the injector under cavitating conditions. Cavitation and flashing are observed to follow similar trends. As such, they appear to be related phenomena, and this relationship is shown. Bubble formation under cavitating or flashing conditions is observed to attenuate the injector's discharge characteristics. High-speed videos of the flow field were also collected. Several flow regimes and flow structures, unique to these regimes, were observed. The results suggest a possible way to predict an injector's performance under flashing conditions without running heated fuel through the injector. These results may be applicable to real world injector design and testing.
