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

Краткое описание

In this experimental study, two conical and one cylindrical diesel injector nozzle orifice geometries were compared to each other. Contrary to earlier studies, the outlet diameter of the conical orifice was constant in all nozzles The main objective of the present study was to examine the effects of conical nozzle orifice geometry on fundamental spray characteristics when the outlet diameter is constant and independent of conicality. The spray tip penetration, spray angle, and mass flow rate were investigated, analyzed, and compared to different nozzle orifice geometries. The literature review shows that while the influence of conical nozzle orifice geometry on spray characteristics has been examined in several studies, some contradictions could be identified from these studies. This suggests that the topic is not comprehensively understood. Experimental fuel spray measurements were performed with a laser based backlight imaging system in a pressurized injection test chamber at room temperature. The density of ambient gas was 36 kg/m3, which corresponds to the density in real diesel engine conditions at the end of a compression stroke. A clear difference was not found when non-evaporative spray tip penetration was compared to different conical and cylindrical nozzle orifice geometries. This is inconsistent with earlier studies where spray tip penetration was studied. The spray angle was narrower with conical, rather than cylindrical, nozzle orifice geometry and the mass flow rate was notably higher with conical nozzle orifice geometry, which is consistent with earlier studies.
