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

RÉSUMÉ

Emulsion fuel is a mixture of fuel and water which can reduce nitrogen oxide (NOx) and particulate matter (PM) in an exhaust gas when it is burned by a diesel or other heat engine. However, emulsion fuel has low stability because oil and water can easily be separated. In this research, a bubble pulse caused by an underwater explosion is used to emulsify samples. This mechanism of emulsification is observed by a high-speed video camera and clarified. In this experiment, the sample is composed of a bio-diesel fuel, water, and air. The sample and detonating fuse are set under the water, and a high-speed video camera is set in front of the observation window. The underwater explosion is later caused by igniting the detonating fuse. Since the video camera is not able to record the shock wave, the explosion gas and actions inside the sample are mainly observed. Results show how the underwater explosion affects the process of emulsification. From the captured video, it is clear that compression and expansion movements of explosion gas affect the process of generating emulsion. Also, the movement of bubbles is observed during the expansion and compression in the sample.
