某水电站泄水道三维数值模拟分析OA

Based on the FLUENT,the standard turbulence model was used to establishes a 3D mathematical model of discharge channel of a hydropower station,To verify whether the ecological discharge of the discharge channel of a hydropower station project meets the requirements,and to study the hydraulic characteristics of the ecological drainage channel,such as flow capacity,water velocity along the course,pressure distribution,and jet trajectory length.the simulation of free surface was done by the VOF(Volume of Fluid)method;and the SIMPLE(Semi-Implicit Method for Pressure-Linked Equations)algorithm was used to solve velocity and pressure coupling equations.The numerical simulation results are in good accordance with the results of the hydraulic model test,which further verify the rationality of the design of the discharge channel size.Furthermore,it puts forward practical reference for the body shape design.
