Abstract

The detailed investigation of the flow behavior around the circular and square cylinders has important engineering applications. In the present work, the characteristics of flow in the downstream of three different models with the circle and square cross sections are investigated in the WIND TUNNEL using the HOT WIRE ANEMOMETRY. For the model with a square cross section, the experiments were performed for both zero and 45-degree angle of attack. In this study, the effects of different REYNOLDS NUMBER and the cross-section of the cylinder are studied with the use of measured velocities and their fluctuation components. The Strouhal number and other flow characteristics in the downstream of the cylinder are compared to the published results in the literature. A good agreement is observed between the present results and the reported results. Comparing the results of three models showed that the reduced flow velocity behind 45 degrees orientated square cylinder in the interval X/D<4 are higher than two other models. In addition, the results reveal that the velocity fluctuations behind the square cylinder at zero incidence in the interval X/D<2 are higher than those for the other models.
