Hybrid Simulation of Hydrodynamics of Hydroelectric Power Plant Spillway Structures
The results of applying a three-dimensional numerical model of a viscous liquid to the problem of calculating the parameters of surface spillways are presented. The model takes into account the pressure distribution profile over the flow depth, which is different from the hydrostatic one. The k – ε-model of turbulence is used to close the equations of hydrodynamics. Vertical flow sampling is performed using an adaptive multilayer mesh. The main attention is paid to the verification of the numerical model on the available analytical solution and on the results of physical experiments. It has been established that the numerical model reproduces well the discharge capacity of surface spillways and the conditions of the pools interface. Agood consistency of the pressure profiles on the spillway face obtained in the physical experiment and on the numerical model, as well as the flow parameters that determine the conditions of the hydraulic jump flooding, is shown using the example of the Zhiguli HPP spillway.
