Abstract

In this study, the effects of corner’s form on the turbulence parameters sequence of square cylinder in 0°, 15°, 30°, 45° angles of attack and Reynolds number 8800 has been investigated experimentally. The chosen models are made of plaxy glass, and include 15 mm side length and 400 mm length.To investigate the form influence of different corners on turbulence parameters sequence of square cylinder,three cylinders were used, having form of sharp, rounded and chamfered corners. The chamfering and rounding radius of the corners is selected as 2.5 mm. the results show that the angle of attack and the form of cylinder`s corners cause to important changes on the turbulence parameters sequence of square cylinder and the value of drag coefficient.
