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

ABSTRAKT

The effects of the internal flow in a DI diesel injection nozzle on the atomization of a spray were analyzed experimentally and numerically. Flow visualization studies were made using a transparent acrylic model nozzle. Water instead of diesel fuel was used as the injection liquid. The nozzle geometry was scaled up ten times and the injection pressures for the model nozzle were carefully scaled up so as to achieve a Reynolds number at the discharge hole the same as the diesel nozzle. A polystyrene tracer, a stroboscope, and a still camera were used to visualize the flow pattern in the region of the sac chamber and the discharge hole. The simulation results showed approximately good agreement with the experimental results. When the needle lift was small, the high turbulence in the sac chamber generated by the high velocity of the needle seat flow makes the spread angle of the spray plume large. By locating the discharge hole on the upper side of the sac chamber, the turbulence intensity in the sac chamber increases and the spread angle of the spray plume becomes large. Cavitation, which arose from the sac chamber, makes the spread angle of the spray large but the discharge coefficient small.
