description | The hydraulic jump is a natural phenomenon occurs in steep waterways and behind the heading up structures. The main benefit of the hydraulic jump is dissipating the excessive kinetic energy. Tools such as sill, baffle blocks… etc. are used to maximize the energy loss through the hydraulic jump. In the present study, screens with a constant height and width are located downstream the gate at a constant relative distance and examined under the different conditions of submerged hydraulic jump. Screens with different relative holes area are tested to select the best screen relative area. Screen with relative holes area of 0.285 had a maximum energy loss and shortest length with a minimum tail water depth of the submerged hydraulic jump. The theoretical derived equation of the relative depth of the hydraulic jump had a higher asymmetric scatter with the experimental results around the line of equality; however an acceptable agreement was present when a correction factor was used. |
