Swirling flows are related to spiral motion in the tangential direction in addition to the axial and radial direction using several swirl generators. These kinds of flows are used for combustion chambers to improve the flame stability, heat exchanger enhancing heat transfer coefficients, agricultural spraying machines and some vertical pipes to move slurries or conveying of materials. But, few papers have dealt with three dimensional velocities profiles in a vertical pipe. In this paper, 3 dimension PIV technique has employed to measure velocities profiles in water along a vertical circular pipe for Re = 3000 ∼ 13,000. The swirl generator to be used is tangential inlet condition to produce the flow. The velocities and flow noise have been measured with swirl in the water and air along the test tube.
