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: 1.1 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: 1.3 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: 0.0002 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: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

SINOPSIS

To understand the disintegration phenomena of cylindrical liquid jet co-flowing with high speed air stream in the nozzle, the disintegration mechanism depending on the coaxial air flow introduced to the liquid jet was experimentally investigated with twin fluid atomizers made of glass. This study focused on the effects of the dimension of the mixing tube, the liquid and air flowrate on flow patterns, the disintegration mechanism of liquid jet, and the pressure variation of nozzle interior.
When the air stream was supplied to the longest smooth liquid jet, flow patterns in the nozzle interior were observed for various diameters of mixing tubes and liquid jets. For the nozzles where the through-flow of liquid jet was obtained, the maximum breakup length according to the ejection velocity of liquid jet was seen at Rel = 2100 and the minimum at Rel = 4500. The former Reynolds number indicated the boundary between the laminar jet and transient jet, and the latter Reynolds number indicated the boundary between the transient jet and turbulent jet. When air flowed coaxially along the liquid jet, the breakup length generally decreased drastically. On the contrary, there existed a region where the breakup length increased even though air was supplied to the liquid jet. This phenomenon was observed in the region of the droplet flow. The pressure within the nozzle peaked at the boundary region of transient flow and turbulent flow where fluctuation of the liquid jet was most severe.
