Application Research of a High Turbulence Numerical Simulation Technique in a USBR Type III Stilling Basin

In view of the energy dissipation design of the USBR Type III stilling basin, which is characterized by intense turbulent flow and complex flow patterns, a reliable mathematical model and calculation method is used to track and record the changes of flow parameters during fluid movement. The results of flow movement can be obtained, and the changes to the whole and local parameters of the flow field can be accurately simulated. Using the case of the discharge sluice stilling basin of the flood storage ecological treatment project of Jinchang Industrial Base in Gansu Province, this paper simulates the flow pattern through numerical calculation, thereby saving labor and material costs. The design cycle is also greatly shortened compared with the physical model test, and the technique has good repeatability, controllability, convenient optimization design, and provides technical support and quality assurance for complex energy dissipation problems.
