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: 0.6 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: 0.6 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: 0.00013 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: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

ABSTRAKT

The correlation between the development of atomization and flow field in a liquid jet was investigated. A fuel injector is widely used for internal combustion engines, and injection with high-quality atomization is vital for better thermal efficiencies. The present study aims at establishing a research approach for finding the fundamental mechanism of atomization enhancement. A simple two-dimensional nozzle was designed and a liquid jet flow was visualized by using a high-speed camera system. An evaluation index of atomization by means of image analysis was proposed. The proposed approach is based on an idea that the essence of atomization in fuel injection will be the ratio between the surface area and the volume of a fuel. The evaluation index enables us to know the degree of atomization quantitatively, so that the procedure of atomization enhancement has been clarified. The velocity field was obtained by applying the PIV analysis to a visualized image, and the correlation with atomization enhancement was examined. Fine linear relationships between the progress rate of atomization and standard deviation of velocity gradients were found. The fundamental mechanism of the atomization enhancement was discussed based on the obtained evaluation results.
