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

ABSTRACT

The paper discusses some fundamental spray properties and new aspects of measuring the spray behavior. The fuel injection measurements were done with marine common rail diesel injection equipment under nonevaporating conditions in a pressurized test rig. The tests were made at room temperature to ensure a constant environment for the sprays and to study the fundamentals of transient fuel jet. Fuel injection was performed with 1400 bar pressure to 35 kg/m3 ambient gas density with different nozzle orifices. Some fundamental phenomena in dense and high-velocity diesel spray can be confirmed by short exposure spray imaging. Imaging was based on planar illumination and digital imaging. The main findings were high-definition shockwave images. Shockwaves can be seen when the supersonic fuel spray exits the nozzle orifice. Shockwave imaging is used to estimate the velocity difference of the fuel and ambient gas. Boundary layer velocity measurements are shown at the vicinity of the nozzle orifice. Velocity measurements can be used to estimate nozzle discharge coefficients. The initial laminar core flow of the liquid and the collapse of this initial region were recorded. This may seem like a rather unlikely phenomenon in diesel injectors and it can well be considered as a special case. Spray-to-spray variation of the spray exit has also been recorded. Some time scales of the transient spray phenomena are also drawn.
