摘要：
The effect of swirling on the flow characteristics of tubes with sudden expansion is experimentally examined by 3D particle image velocimetry technique to determine velocity profiles. The swirling flow of water in sudden 1:2 axisymmetric expansion has been previously studied within a horizontal round tube. A tangential slot is used as a swirl generator for swirling flow, whereas a honey comb is used for flow without swirling. Three velocities with swirling flows are compared along the test section at Re=14800, and the streamline in the recirculation zone is described.
