Abstract

Lateral intake is a hydraulic structure which is broadly used for purposes such as agricultural consumption or urban water supply. To improve the efficiency of this structure, it is common to install a submerged vane near the entrance of this structure. Despite common applications of this structure, there is still a lack on correct description of flow structure near this structure and the variability of flow characteristics due to the geometrical characteristics such as lateral intake angle. In present study, we numerically investigate the role of submerged vane and lateral intake angle on flow structure using FLOW-3D simulation package. The results show that the lateral intake with 45° angle has the highest efficiency which can transport the highest amount of water together with lowest amount of sediments to the lateral intake. Moreover, it is also found that formation of a circulation zone between submerged vane and main channel lateral wall causes a high amount water to enter to the lateral intake with the lowest amount of sediment. Finally, simulations of flow in the presence of two submerged vanes show that two submerged vanes installed in a straight line and in a parallel configuration have higher efficiency in conveying water to lateral intake with low amount of sediment.
