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

摘要

This study presents the development of a new spray model that captures the full polydisperse nature of spray flow without using drop size classes. In this model, the size information concerning the spray is obtained by calculating three moments of the drop size distribution function from transport equations and one moment from a Gamma distribution function. The method reduces the need to presume a particular distribution function for the drop sizes and the complexity of the solution scheme. Drop size data obtained from the examination of the structures of a free spray using a laser-diffraction-based drop analyzer were used to further develop the new spray model and determine its ability to accurately predict such sprays. Test results include the axial distributions of the radial-averaged drop sizes and the local drop distribution at axial positions, and indicate that the drop size distribution is dependent on the atomizing air pressure of the injector and the position of the drop from the injector nozzle. At higher pressure cases the distributions were observed to be bimodal. These trends are captured by the computational results and compare well with those from another moments spray model.
