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

A new similarity solution for spray distribution in a boundary layer flow, involving an imaginary-valued variable, is presented. The flow field similarity solution has three branches, the two known solutions for accelerating flow and moderately decelerating flow and a new solution, which is the focus here, for high-rate deceleration. This last family of solutions involves the use of imaginary expressions in the course of the similarity procedure. Although the procedure employs imaginary expressions, the solution in the physical plane admits a fine behavior. The mass distribution of spray droplets in the boundary layer for the latter case shows that the highest concentration is either at the wall or at the edge of the boundary layer, depending on the nature of downstream variation of the aerosol concentration at the outer flow and on the particular branch of the flow solution. The new similarity solution presented here opens the possibility to describe a new range of boundary/shear layer problems. We demonstrate that the option for describing droplet/particle distributions in such configurations has ramifications for transport and deposition of droplets/particles in boundary layers developed in industrial facilities and sizing instrumentation, and we suggest its possible application for cases of spray-surface interactions.
