Numerical Simulation of Flow Diversion from an Intake at a Main Channel with Vertical and Inclined Bank Using Fluent

Abstract:
The study of flow diversion in open channels is one of the most important subjects for hydraulic engineers. In the present study, the diverted flow width at a 90 degrees intake which had been installed at a main channel with vertical and inclined bank was investigated using experimental and numerical models. The main goal of this study was to investigate the effect of main channel side slope on the diverted flow width. The calibration and verification of the numerical model were done by experimental data. By analysis of the data, the diverted flow widths were determined and compared for the different depths. The results showed that, in the inclined bank, the diverted flow pattern was modified in such a way that the diverted flow width increased at the surface and reduced at the bottom.Also in the side slopes of z=1 and 1.5 the diverted flow width in surface relative to bed was 1.8 times higher. Finally, analysis of flow pattern showed that the optimal side slopes were z=1 and 1.5.
