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

The purpose of this study was to investigate the flow and atomization characteristics of an impinged spray on the wall of a chamber with a high-speed diesel spray injected from a common-rail system under various experimental conditions. The flow characteristics of the impinged spray were visualized and the droplet velocity distributions were obtained using a particle image velocimetry (PIV) system. The atomization characteristics of an impinged spray on the wall were investigated in terms of mean droplet size and radial mean velocity at various injection and wall parameters such as injection pressure, ambient pressure, the nozzle-wall distance, and the inclined angle of the wall. Additionally, the velocity distributions from the PIV system were compared with the measured results of the phase Doppler particle analyzer (PDPA) system. It is revealed that the radial spray penetration and the flow field on the impinged wall increase with the increase of the injection pressure and inclined angle of the wall. Comparison results of radial velocity on the impinged spray between PIV and PDPA show that the maximum value of radial velocity is similar. The distributions of SMDs under various experimental conditions show that atomization characteristics are affected by high-momentum droplets. The increases of injection pressure and nozzle-wall distance cause the decrease of droplet diameter, and measured droplet diameters are mostly under 25 μm.
