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

SINOPSIS

The external flow field and the aeroacoustic generated by automotive appendices such as the A-pilar rain gutters and outside-rear-view mirrorrs are simulated using Large Eddy Simulation (LES). In the present study the simulations were carried out for three rain gutter geometries and two different mirror models. In these cases the simulation results were compared with the existing experimental data. For the flow around the gutters the agreement was found to be very good (for all three configurations) for the entire range of frequency measured. In addition, the present numerical simulations appear to be more accurate than previously published results obtained for the same geometries using RANS approach. Finally, the simulations of two outside rear view mirror configurations on a flat plate were completed. Calculations carried out on coarse and fine grids were compared to experimental data. In this case averaged pressure and velocity magnitude were compared again demonstrating the accuracy of the present approach.
