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

This paper presents a simulation study of the internal flow of a self-pulsating injector adapted from the design of the Coanda-effect bistable feedback fluidic oscillator. The computational fluid dynamics (CFD) method is used to study the effects of geometric parameters on pulsation characteristics. The influence of four factors on the oscillatory flow field is examined: the specific value of the outlet height to the joint inlet height (α), the specific value of the length to the height of the amplifier channel (β), the inlet velocity (Vi), and the fluid material. Focus is concentrated on the influence of these factors on oscillation frequency and amplitude. It is found that the variation of both oscillation frequency and amplitude with inlet velocity is independent of fluid material. The effects of geometric change on the oscillator are presented, which are of instructive significance for the practical design of a self-pulsating injector. In addition, the linear response regime, where oscillation frequency is perfectly linear with respect to Reynolds number, is successfully reproduced in these simulations.
