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

RÉSUMÉ

With a focus on the direct-injection gasoline (GDI) engine, this work provides near-wall spray details of the liquid phase of an impinging fuel spray at GDI engine conditions. The experiments are conducted in a constant volume pressure chamber at elevated gas pressure (pgas = 0.6 and 1.5 MPa), increased gas temperature (Tgas = 500 K), and variable wall temperature (Tw = 400 and 575 K). Using phase-Doppler anemometry, temporally and spatially resolved mean droplet sizes and velocity components are determined at distances from 0.2 to 1.0 mm above the surface. The transient behavior of the wall jet, which develops along the surface, is resolved by the measurements. The formation of a vortex at the front of this jet is observed. At its tip, large mean droplet diameters are observed that coincide with a rapid change of the wall-normal velocity. An increasing wall temperature causes the tip of the wall jet to propagate slower along the wall, which is apparently caused by a change in the local density of the gas above the surface.
