Abstract

Occurrence of the vortex in Hydraulic structures as a natural problem has negative effects on the performance of the intakes. In order to better understanding this complex phenomenon, in addition to macroscopic studies on Critical submergence and anti-vortex devices, microscopic studies are also employed to investigate the hydraulic properties of a vortex. In the present study, a strong Air-core vortex under Critical submergence condition was created on a vertical bottom intake at a wide flume then the three-dimensional velocity components of the flow were measured by a particle tracking velocimetry method. By analyzing the velocity components and water surface profile, the changes of the hydraulic characteristics of the vortex in the flow path were identified and a new information from a 3D vortex structure with the air core was obtained. Based on the results, it was found that the Particle Tracking Velocimetry (PTV) method can provide useful and new information about distribution of the velocity components in the vortex structure.
