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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

ABSTRAKT

In this study, an experiment was carried out to understand the behavior of incompressible flow passing through the plain orifices of a pintle injector to characterize the discharge coefficient (Cd) for different orifice geometries. Three various orifices, including primary, secondary, and film-cooling orifices, were utilized to characterize the discharge coefficient and understand each orifice flow pattern with high-speed imaging. Each of these orifices was separated and tested in their test article. The impacts of parameters, including shape and size, on discharge coefficient, were studied. The discharge coefficient of each test article was determined by subjecting the orifices to a range of flow rates and measuring the pressure differential. The results obtained for the test article F show a good agreement with the choked fit curve obtained from the analytical relation. In contrast, the results of other test articles show an inconsistency due to the flow instability as an unstable flow in their trends.
