“…Their study neglect the pressure in the vicinity of square corners, therefore there is a little difference in the drag coefficient value. When results for the square cylinder with splitter plate at L/D = 1 are compared to the study of Sarioglu et al (2006), the drag coefficients show substantial differences. Sarioglu et al (2006), also did not consider the pressures acting on the splitter plate, even if it is of utmost importance.…”

“…The lift coefficient (C L ) is defined as C L = (2F L )/A , where F L is the net lift force acting on the model. C L of the square prism with/without the plate for the present study and the study of Sarioglu et al (2006) are shown in Figure 4 at Re = 20000. For the square cylinder alone, lift coefficient results of present study are in good agreement with that of the study of Sarioglu et al (2006) except for 10<< 30 and 100<< 120.…”

“…A moving surface (Zhang et al 2010), a dielectric barrier discharge actuator (Akansu et al 2013;Akbıyık et al 2016), suction and blowing (Li et al 2003), a vortex generator (Volino and Ibrahim 2012) and a piston cylinder mechanism (Gilarranz et al 2005) can be given as examples of AFC methods. Splitter plates (Akansu et al 2004;Sarioglu et al 2006), passive vortex generators (Godard and Stanislas 2006) control rod (Akansu et al 2011;Fırat et al 2015;Sarioglu et al 2005) and dimples (Bearman and Harvey 1993) can be listed as examples of PFC methods. Sarioglu et al (2006) studied the influence of adding a plate to a square prism with ratio L/D=1.…”

Lift and drag forces on a square prism with a (splitter) plate are experimentally investigated by force measurements with a load cell. Results showed that drag and lift coefficients are independent of Reynolds number for Re = 9700-36500 at 0°, 45°, 90°, 135° and 180°. Drag coefficient at 0 is obtained as 2.02 for the square prism alone, and 1.04 for the square cylinder with splitter plate. Maximum drag reduction for the square cylinder with the plate is 50% as compared to the square cylinder at 0 and 15. For α < 30° and α > 114°, drag coefficient of a square prism with splitter plate is smaller than that of the square prism alone. At Re = 20000, lift and drag coefficients significantly change with increasing attack angle.

The flow characteristics around a symmetrical airfoil NACA 0012 at incidence and a circular cylinder placed in tandem have been studied experimentally at a Reynolds number of 1.510 5 based on the chord length of the airfoil C. The downstream circular cylinder of diameter D = 25 mm used as a bluff body was placed in the same axis in the flow direction in the wake of the airfoil. The dimensionless gap S/D, where S is the longitudinal spacing between the airfoil and the cylinder, and the attack angle of the airfoil, , were varied from 0 to 4.3 and from 0° to 15°, respectively. The effects of the attack angle of the airfoil and the longitudinal spacing between the airfoil and the cylinder on the pressure distributions and vortex shedding were examined. Characteristics of the vortex formation region and locations of flow attachments, reattachments, and separations were observed by means of the flow visualizations. It has been seen that the airfoil and the cylinder have considerably affected by each other. The variation in the flow structures according to the attack angle of the airfoil and the longitudinal spacing between the airfoil and the cylinder are revealed utilizing the flow visualization photographs.Keywords: Airfoil, circular cylinder, aerodynamic characteristic, pressure distribution, Strouhal number BİR KANAT PROFİLİ VE BİR DAİRESEL SİLİNDİR ETRAFINDAKİ AKIŞIN AERODİNAMİK KARAKTERİSKTİKLERİ ÖZArdışık olarak yerleştirilmiş simetrik bir NACA 0012 kanat profili ve bir dairesel silindir etrafındaki akış karakteristikleri kiriş uzunluğuna göre tanımlanmış Reynolds sayısının 1,510 5 değerinde deneysel olarak incelenmiştir. Bir küt cisim olarak kullanılan 25 mm çapındaki dairesel silindir, kanat profilinin iz bölgesinde akış yönünde aynı eksende yerleştirilmiştir. Boyutsuz boşluk S/D (burada S, kanat profili ile silindir arasındaki uzunlamasına boşluktur) ve kanat profili hücum açısı, , sırasıyla 0'dan 4,3'e ve 0°'den 15°'ye kadar değiştirilmiştir. Kanat profili hücum açısının ve kanat profili ile silindir arasındaki uzunlamasına boşluğun basınç dağılımı ve girdap kopması üzerine etkileri incelenmiştir. Girdap oluşum bölgesi ve akış tutunması, tekrar tutunması ve ayrılma konumları, akış görüntüleme yardımıyla gözlenmiştir. Kanat profili ve dairesel silindirin önemli derecede birbirlerini etkiledikleri görülmüştür. Kanat profili hücum açısı ve uzunlamasına boşluk mesafesine göre akış yapılarındaki değişim, akış gözlem fotoğrafları kullanılarak açıklanmıştır.Anahtar Kelimeler: Kanat profili, dairesel silindir, aerodinamik karakteristik, basınç dağılımı, Strouhal sayısı * Corresponding author / Sorumlu yazar.
