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

要約

Piezoinjectors with outwardly opening nozzles are the latest generation of high-pressure injectors for gasoline direct injection (GDI). In this study, a combined Eulerian-Lagrangian spray model is presented, which is based on user-defined implementations of all key models within a Fluent framework. Primary and secondary breakup is modeled with a combined LISA-KH-TAB approach. The LISA primary breakup model is extended by a one-dimensional model of the nozzle flow and by modified momentum source terms that lead to a more reasonable prediction of the near-nozzle continuous phase flow field. The KH and TAB secondary breakup models are applied to high and low Weber number secondary breakup, respectively. The collision model implemented accounts for all relevant collision regimes (i.e., coalescence, stretching separation, reflexive separation, and bouncing). For the bouncing and reflexive separation regimes, the momentum equations are modified because the standard equations cannot predict the trajectories after off-center collisions of differently sized droplets. Vaporization is modeled with a single-component model, which employs an analytical solution of the coupled heat and mass transfer equations. The combined model is validated with light scattering visualization and light sheet measurements, phase-doppler anemometry (PDA), and laser correlation velocimetry (LCV) at pressurized vaporizing- and nonvaporizing conditions. The validation indicates a good agreement of both macroscopic and microscopic properties, such as the spray geometry, vortex positions, or drop size distributions.
