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

摘要

In this article, numerical and two dimensional study flow field around NACA0012 airfoil with making geometrical changes is discussed. In order to investigate geometrical changes on airfoil and its effect on aerodynamic performance of the airfoil, design of making step on airfoil have studied. For this purpose, once step at upper surface and once simultaneously at both sides upper and lower surfaces of the airfoil, have considered. The calculations were performed at Reynolds number of 160000 and lift and drag coefficients and lift to drag ratio at stepped airfoils with unmodified NACA0012 airfoil is compared. Also streamlines and separation of flow around airfoils and stall angle have discussed. Results indicate significant changes in airfoil aerodynamic performance as with making step at upper surface airfoil stall angle is delayed and lift to drag ratio is increased at some angles of attack. Also with making step at both sides upper and lower surfaces of the airfoil, lift coefficient increased compare to airfoil without step, especially at low angles of attack.
