Abstract: An experimental study of the effects of the cylinder spacing and angle of incidence of a pair of rectangular cylinders with round leading edge but square trailing edge on the wake dynamics in an open channel turbulent flow is reported. The cylinder pair was inclined at θ = 0°, 10°, and 20°. Three centre-to-centre spacing (b = 30 mm, 50 mm and 75 mm) were investigated for each cylinder pair inclinations. Particle image velocimetry was used to conduct measurements around each cylinder pair. The results show that the mean velocity and the turbulence level increases with decreasing spacing and increasing cylinder inclination to approach flow.
