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

In order to reduce the aerodynamic drag of a vehicle door mirror, the tip shapes of the door mirror are improved by using ditch and concavity in this study. Their aerodynamic drag and the flow structures are quantitatively evaluated. It is found that the aerodynamic drags of the door mirrors can be reduced by the tip shapes of ditch and concavity. The PIV technique was used to measure the instantaneous velocity fields of the mirror wake and the distribution of time-averaged streamlines and Reynolds stresses are examined. Furthermore, the instantaneous turbulent structures are decomposed into the multi-scale structures by the wavelet multi-resolution technique and the distributions of multi-scale Reynolds stresses are analyzed. It is evident that the Reynolds stresses of the small-scale structure can be reduced by improving the tip shape with ditch or concavity.
