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

ABSTRAKT

The present study performs an extensive numerical study for analyzing the anisotropic turbulence effects on spatial and temporal behaviors of diesel sprays after wall impingement. The Durbin (P. A. Durbin, Int. J. Heat Fluid Flow, vol. 14, no. 4, pp. 316−323, 1993) k−ε−ν2 model is used to simulate the anisotropic turbulence effects and its results are compared with the predictions by the k−ε model based on the isotropic assumption. In the present study, the Lee and Ryou (S. H. Lee and H. S. Ryou, Atomization and Sprays, vol. 11, pp. 85−105, 2001) model is used for the calculation of the spray-wall interactions. The predicted results by two turbulence models are compared with several experimental data for both the overall structure of impinging sprays and the internal structure, for which the main parameters are the radius and height of impinging sprays, the local velocities and the Sauter mean diameter of droplets, the local velocities of gas-phases, and so on. The k−ε−ν2 model considering the anisotropy of turbulence predicts both gas and droplet tangential velocities better than the k−ε model does. It is concluded that the anisotropy of turbulence should be considered in simulating impinging diesel sprays.
