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

The concept of coaxial porous injector design for gas-liquid mixing involves improved momentum transfer between the gas and liquid jets by changing the gas injecting direction of a conventional liquid-centered shear coaxial injector from parallel to perpendicular using porous material. Cold-flow tests of the coaxial porous injector and the shear coaxial injector in two-dimensional configurations were carried out to compare the macroscopic characteristics of sprays from each injector and to understand the effects of spraying conditions on the breakup length and the spray angle. The spray patterns were visualized using the shadowgraphy technique. The shadowgraph images recorded in high speed were post-processed to detect the breakup length and the spray angle. The post-processing code filters the dynamic pixels, and leaves the stationary pixels, which corresponds to the liquid core and the background. The most significant differences between the porous injector and the shear injector in the two-dimensional configurations were the spray angle and the uniformity of the disintegrated liquid jet. The liquid column from the shear injector was not split off entirely, and only the portion at the interface between the gas and liquid jet was atomized by the shear force. On the other hand, the liquid jet from the porous injector dispersed more widely, and was disintegrated into droplets more completely in most experimental cases of similar axial momentum flux ratio conditions at the injector tip, and it was thought that an optimal porous element length for the best mixing performance exists at certain injection conditions.
