Abstract

Stilling basins are one of the most common structures for energy depreciation of flow with high velocity that among different sections and types of these basins, diverging stilling basins have better hydraulic performance and lower constructional costs. In this research, numerical modeling capability of diverging Hydraulic jump on the reverse slope was investigated using FLOW3D software. Experimental model data was used at divergence angles of 5 and 10 degrees in diverging angels of 1. 3, 2. 35, 3. 2, 4. 57 degrees in addition to classic Hydraulic jump. The outputs of simulation model in comparison with the results of experimental data indicated that the model shows the amount of water surface profiles, jump length and maximum velocity in depth with good accuracy. The results showed that the mean relative error of water depth obtained from numerical model and measured values is about 15 percent. The velocity profiles were also in good agreement with the measured data.
