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

要約

Superheated, or flash, atomization is a highly complicated process. Important factors characterizing the effectiveness of the spray breakup and the quality of the resulting spray are the mean droplet diameter and spray temperature. The smaller both quantities get, the more intense is the disintegration of the liquid. The determination of the spray liquid temperature is often conducted with thermocouples. This measurement method is disadvantageous owing to its invasive character that induces disturbances of the liquid flow. To improve the temperature measurement, linear Raman scattering is used. This laser-based, noninvasive measurement method allows the determination of the spray liquid phase without considering the gas phase. In this work, it is for the first time applied to characterize the development of liquid temperature in a spray generated by flash atomization. Shadowgraphy is used to assign the predominating break up mechanism to the corresponding spray temperature evolution. Furthermore, droplet diameters are measured with laser diffraction. The evaluation of linear Raman spectroscopy for the analysis of the spray temperature in combination with the description of spray characteristics are the outlines of the article. The results show that droplet temperatures can be determined with linear Raman scattering, yielding a lower spray temperature for higher applied superheat.
