Numerical Simulations of the Fish Passage Facilities at Lower Granite Dam

Abstract

The purpose of these numerical simulations is to investigate possible modifications to the fish diversion facilities currently installed at Lower Granite Dam. These modifications are intended to refine the flow field just upstream of the powerhouse thereby improving the juvenile salmonid attraction potential. A pressure-based finite volume, computational fluid dynamics code was utilized to solve the Reynolds-averaged Navier-Stokes equations. The computational grids, comprising between 350,000 and 1,000,000 nodes, simulated a region encompassing the entire dam geometry as well as 5000 feet upstream. This report describes the numerical model, model boundary conditions, numerical grid and general flow field dynamics obtained from the study as well as providing recommendations for future work pertaining to numerical studies of surface collection facilities.
