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

A new collision model with improved physical accuracy and reduced numerical dependency has been developed and is used for engine spray calculations. A radius-of-influence of collisional interaction approach was employed along with dynamic discrete particle resolution improvement to reduce numerical dependency. The collision outcomes considered include bounce, coalescence, and fragmenting and nonfragmenting separation processes. The improved collision probability and outcome predictions were coupled to form a comprehensive model that was used to simulate nonvaporizing diesel sprays produced under conditions relevant to common-rail diesel injection systems. Spray penetration results from visualization studies, and drop-size and velocity data from phase Doppler particle analyzer measurements were used to assess the capability of the model for different injection pressures and various chamber densities. The predictions were reasonably good, indicating that the present improvements to collision modeling have increased the fidelity of spray modeling predictions, and are consequently expected to help improve the accuracy of multiphase flow simulations.
