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

RESUMO

An experiment was carried out on the structure of a twin spray from two pressurized-type swirl nozzles, in order to investigate the overlapping spray characteristics of two single sprays. Using image processing methods, spray characteristics such as the droplet size distribution and number density of the spray were investigated in order to obtain design data for an ice-slurry making system. The flow rate distribution of the overlapping sprays in a horizontal plane was also measured. In the present study, a relatively simple twin spray was studied experimentally to investigate the droplet size distribution and the velocity of droplets in the overlapping spray region. By comparing experimental results of the twin spray with those from two single sprays, the flow rate was concentrated in the region of overlap between x = 0 and 50 mm, where there was vigorous interaction between the two sprays. Comparing the measured Sauter mean diameter (SMD) of the twin spray with that of the single spray, no substantial difference in the SMD distributions was found over the whole range of the spray from nozzle L (serial number 6032). The maximum SMD of both results was 60 μт, which was located at the middle of the overlapping region. The twin spray showed a different distribution of the number density due to the collision between spray droplets. For the twin spray, the number density was slightly increased in the overlapping region of 15−35 mm. However, it became rather smaller at the periphery of the spray, where the influence of collision between droplets was small For a larger-sized nozzle, the number density of the twin spray was clearly higher, by 20%. This is mainly because the spray from nozzle L had a larger flow rate and higher density. Consequently, the collision of droplets in the overlapping region suppressed the movement of large droplets to the periphery.
