Experimental investigation of 90° intake flow patterns with and without submerged vanes under sediment feeding conditions

چکیده
In this study, two experiments were conducted in a 90° water intake to study 3D flow patterns and sediment distribution using submerged vanes under feeding live-bed conditions. One column three installed at 20° angle maintaining for discharge ratio of q r ≈ 0.1. Three-dimensional mean turbulent velocity components channel measured acoustic Doppler velocimetry (ADV). Flow characteristics the structure area with no compared these Results showed that single reduced amount by 20% during diversion. downstream corner intake, high velocities where scouring occurred. The affected intensity secondary flow, turbulence energy, separation, moved deposition main channel.

Experimental Investigation on the Deviated Sediment and Flow to Sediment Bypass Tunnels (SBTs) Using Submerged Plates
Sediment Bypass Tunnels (SBTs) are deviant channels that convey the current containing sediments from the upstream of the reservoir to the downstream of the dam. In this research, by applying submerged plates on the entrance of a 90-degree diversion channel for sediment transport, the effect of hydraulic parameters of flow and changes in the angle of plates on sediment transport and deviated fl...

One of the methods for sediment control in lateral intake can be application of submerged vanes in front of the inlet. The establishment of submerged vanes in flow path causes a flow diversion toward the inner arc. In this research, the performance of submerged vanes on sediment transport to the inlet at 180 degree of intake has been investigated. Several experiments were carried out in a labor...
