“…The porous wrapper reduces the pressure drop and skin friction which leads to a reduction in drag compared with a solid cylinder of equal radius. As instances for deep water studies, Gim et al [14] studied on flow control by rods of various sizes attached to the rearward stagnation point of a circular cylinder using PIV technique. They performed experiments at Reynolds numbers between Re = 5,000 and Re = 20,000 based on free stream velocity and the main circular cylinder diameter (D = 50 mm).…”

“…On the other hand, many passive control methods are used at the studies since applying passive control methods are easier than that of the active control methods. Gim et al (2011) used control rods to control the flow. They attached the rod to the rearward stagnation point of a circular cylinder.…”

“…Literatürde derin suda, değişik geometrideki cisimler arkasındaki akış yapısı ile ilgili çok sayıda çalışma bulunmaktadır [3]- [10], [12]- [14]. Bu çalışmaların çoğunluğu silindir etrafına yerleştirilmiş delikli silindir, ince plaka, çubuk veya deflektör gibi kontrol elemanları ile daimi olmayan akış yapısının kontrolü ile ilgilidir.…”

“…Yaptıkları deneysel çalışmayı = 10000, ⁄ = 0.6 çap oranı ve = 100 mm/s hız değerlerinde PIV tekniğini kullanarak gerçekleştirmişler ve sonuç olarak kontrol sağlanan en iyi geçirgenlik oranını = 0.5 olarak belirlemişlerdir[1]. Gim ve diğ [12],. dairesel silindirin arkasına yerleştirilen farklı boyutlardaki kontrol çubuklarının akış yapısına etkisini PIV tekniği kullanarak deneysel olarak incelemişlerdir.…”
