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

ABSTRAKT

This article describes the experimental and numerical characterization of capillary fuel injection, atomization, and dispersion of liquid fuel in a co-flowing air stream inside a single venturi tube. The experimental techniques used are all laser-based. A phase Doppler particle analyzer (PDPA) was used to characterize the atomization process, and planar laser-induced fluorescence (PLIF) was used to visualize the breakup and atomization process of the capillary fuel spray.
The PLIF experiments confirmed the domination of aerodynamic breakup mechanism in and the influence of gaseous vortical structures of various scales on the atomization process of capillary fuel spray. The PLIF images displayed a smooth liquid jet surface near the fuel tube exit, with a rough, perturbed surface developing gradually. At low relative velocities, it was observed that the initial dilational waves on the jet surface were followed by asymmetric and sinuous waves before they evolved into curling liquid ligaments and/or droplets, as the relative velocities increased.
The advantages of venturi nozzle are demonstrated in this article in terms of better atomization, more uniform fuel—air distribution, compared with straight-tube nozzles and free jets.
A modified version of KIVA-II was used to simulate the entire spray process, including breakup and atomization. It was concluded that the multidimensional spray calculation can be used as a design tool only if care is taken in the modeling of breakup and wall impingement processes.
