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

ABSTRACT

Cavitation inside the passages of an injector can result in decreased discharge characteristics. This paper describes a flow visualization study to characterize cavitation structures in the flow of methanol through a series of high aspect ratio slot orifice injectors of varying L/DH. Cavitation structures were observed to evolve through a series of regimes corresponding to increased pressure drop across the injector. Specifically, the cavitation region lengthens as pressure drop increases. The lengthening cavitation results in a decrease in discharge coefficient that follows a predictable pattern. As the cavitaton lengthens to occupy the length of the injector and hydraulic flip occurs, the discharge coefficient drops suddenly away from what is predicted. In the cavitating injector other flow structures are observed and described. Also, high speed videos are analyzed for frequency content through the cavitation region. Frequency content appears to be concentrated below 1 kHz, with the majority of content existing below 200 Hz.
