| Abstract: | The flow characteristics of deglecting flow discharge of arch dam on bend were experimentally studied by Velocity Distribution Measuring System and direct read out current meter. It accurately measured flow fields and time average pressure head of bend flow, sluice hole flow and deglecting flow field. The relate laws and characteristics of impact of bend flow for sluice hole flow discharge were discussed by three analyzing experimental data of the three different conditions. The study of impact of bend flow for sluice hole flow discharge can be referenced for in-depth analysis. |
