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

RESUMO

Simulation investigations of flow characteristic in diesel nozzles are basically performed using the simplified and idealized geometry models. Therefore, these simulations are essentially two-dimensional (2D), and unavoidably have deviations from real flow characteristics due to lack of three-dimensional (3D) geometry information. In this study, based on the high energy x-ray CT scan, the inner nozzle structures are measured in detail, and the measurement results are applied to generate the 3D computational meshes. The results of the 2D and the 3D simulations are compared to see the effect of the 3D simulation on the flow characteristics in the nozzles. The investigation results show that because of the rough surface and uneven distributions of geometry parameters in the azimuthal direction of the nozzle orifice revealed by the CT scan, the differences of the flow characteristics between the 2D and the 3D simulations are obvious. They exist at the orifice inlet, the orifice outlet, and along the orifice axis. The improvement of evenness of geometry parameter distributions can reduce the differences between the 2D and the 3D simulations. The 3D computational mesh, which contains more geometry parameter information than the 2D one, can reveal details of the influences of geometry parameters on the internal flow of nozzle, and gain more precise simulation results and insight into the flow characteristics under the real nozzle conditions.
