Abstract
Hydraulic study of a selective withdrawal relief gate is presented. A comparison study between a computational fluid dynamics model, Flow3D, and a 3D hydrodynamic model, EFDC, has been performed. Flow3D is applied to simulate behavior of the flow by using limited compressible flow approximations and RNG turbulence model. EFDC is used to analyze the flow through the inlet using a shallow water solver configured equivalent to 2D Reynolds-Average Navier-Stokes (RANS) equations in vertical plane and Mellor-Yamada Turbulence Closure Scheme. Pressure heads and vertical opening velocity results from both models are compared. Computational fluid dynamic models provide us great insight to determine the hydraulic behavior and flow properties in these complex geometries.
