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

ABSTRACT

A technique for determining the local drop size distribution in liquid sprays is developed. This technique is based on the far-field measurement of the single-wavelength back-scattered light from the spray. A combination of a tomographic imaging technique and the Mie scattering theory is used. The tomographic reconstruction of the spray is realized by using several optical projections, which are obtained by recording the back-scattered light when the spray is illuminated with a coherent and collimated laser beam. Each of these projections corresponds to a specific angular orientation of the spray and a single back-scattering direction. Such an image represents the local time-averaged intensity across the spray for the light scattered in the selected direction. Three tomographic images of the same cross section, corresponding to three different back-scattering directions, are used to determine the local drop size distributions. A log-normal distribution function defined by two variables is assumed, and the scattered light intensity by this distribution is calculated from the Mie theory for the three back-scattering directions. A discrete search technique is then implemented to find the local log-normal distribution that best matches the results provided by the Mie theory and the tomographic images for all three directions. Simulations realized with an axisymmetric spray underline the accuracy of this new method.
