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

SINOPSIS

A new conductivity probe technique is applied to high-speed, pulsed diesel sprays to measure the dimensions and time dependency of the breakup zone. Variations are made of liquid properties, gas density, and orifice size. A flat-plate probe is used to detect the contiguous liquid in the breakup zone. Breakup length is of the order 100 nozzle diameters at engine conditions of gas density, and it increases with increase of liquid viscosity and reduction of gas density. Typically, of the order of 1% of injected liquid is measured to be incompletely atomized at 100 diameters downstream. Some agreement with published correlations for breakup length is found; however, it is shown that liquid viscosity should be included in correlations and analyses of breakup, and not simply the ratio of liquid and gas density as in some previous work. A revised correlation gives reasonable agreement with the new data. The breakup length is found to vary throughout the spray pulse, reflecting, in a complex manner, the time-varying flow rate produced by a conventional injector and pump. Periodicity of the breakup zone structure is noted at frequencies of the order 10 kHz, and this appears to be in accordance with published results using photography and laser anemometry.
