Düz Kanal İçerisine Yerleştirilmiş Kare Şekilli Silindir Ardındaki Akış Yapısı

Abstract

Experiments were conducted to investigate the flow topology downstream of a square-shaped cylinder situated in a straight channel. The critical parameters such as the Reynolds number (Re = 500) and the blockage ratio of the square-shaped cylinder (25%) were determined in light of the literature. A Particle image velocimetry (PIV) system was used to obtain the instantaneous velocity vector map. The flow structures, including the time-mean vorticity distribution, <ω> instantaneous and time-mean streamline topology, Ψ, distributions of streamwise velocity fluctuations, urms, turbulent kinetic energy, TKE are presented with Figures.
