Experimental Analysis of the Effect of Geometric Shape of Submerged Vanes on Sedimentation Flows at Lateral Intake Entrance in River Bends
The separation zone in the entrance of intake channel has no effect on flow discharge but it reduces the effective cross-sectional area of the intake, as well as the bed load, which enters the intake due to low velocity flow deposits in this area. Therefore, knowing the dimension of the separation z...

The separation zone in the entrance of intake channel has no effect on flow discharge but it reduces the effective cross-sectional area of the intake, as well as the bed load, which enters the intake due to low velocity flow deposits in this area. Therefore, knowing the dimension of the separation zone in the lateral intake is very important. One of the methods to control sediment transport to a lateral intake is to use submerged vanes in front of an intake mouth. Azizi et al. (2012) evaluated the effect of cuts on the leading edge of vanes on local scour and the performance of submerged vanes in lateral distribution of sediments. Abbasi and Maleknejad Yazdi (2014) carried out some researches about the impact of sill and submerged vanes on sediment laden flows at lateral intake in straight channels. According to the results, the dimension of the separation zone depends on intake ratio and intake angle, and the effectiveness of froud number in the main channel is negligible. In the present study, different shapes of submerged vanes used in Azizi et al.’s (2012) study were employed to measure the dimension of the separation zone in a bend-shaped flume and the obtained results were compared with the results of Abbasi and Maleknejad Yazdi’s (2014) studies. |
