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

This paper intends to improve the Darrieus wind turbine performance by using a new design of vortex generators. Computational fluid dynamics (ANSYS CFX.15) have been used to simulate the turbine in steady state and incompressible flow with Reynolds number Re = 2.05 × 105. The shear stress transport k−ω turbulence model has been used to complete the governing equations, and the vertical axis wind turbine (VAWT) has been modeled in three dimensions. The geometric parameters' (the vortex generators and their sizes with respect to the profile) influence on the performance of VAWTs is studied. The first part of this work presents the flow behavior around the smooth airfoil, for a different angle of attack, which is compared with experimental data. The second part studies the passive control effect of the vortex generators (VGs) placed first on the extrados, then on the intrados, and finally on the two sides, for different VG heights. This research indicates the VAWT's performance can be greatly improved by correctly choosing the size and position of the VG, in which the smaller height of VG increases the tangential coefficient considerably.
