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

Краткое описание

The present article proposes a new hybrid collision model to analyze the interspray impingement system. The new hybrid collision model proposes a new criterion for the collision threshold and also involves a collision-induced disintegration regime, together with three representative regimes, such as bouncing, separation, and coalescence. In particular, the new collision thresholds are devised to take account of both the preferred directions and the critical distance between the two impinging droplets from literature findings. A cumulative collision number is also introduced to effectively compare the differences between the present model and the original O’Rourke model. The interspray impingement systems are simulated under both low and high pressures of the gas phase, and the predictions are compared with experimental data such as spray shapes, Sauter mean diameter (SMD), and penetration lengths. The present model shows better agreement with experimental data in predicting droplet sizes for the low-gas-pressure case and spray patterns for the high-gas-pressure case than the O’Rourke model does. It is thus thought that the present hybrid model is acceptable in predicting the interspray impingement system effectively.
