A Hydropower Station Energy Dissipation Shape Optimization Test

In this study, hydraulic model testing is used to optimize the flood discharge and energy dissipation body type of some power plant. Compared from the flow regime, bottom velocity, dynamical pressure and so on, it is found that the fluctuating pressure and bottom velocity at the exit side wall stilling pool bottom, are impoved by surface outlet contraction and intermediate outlet contraction, the largest bottom flow rate of surface outlet is about 13.6m/s, the maximum fluctuating pressure of stilling basin is approximately 6.7×9.81kPa. The problem of large bottom flow rate and fluctuating pressure are solved by this testing result, the result provided references for design.
