3D Numerical Flow Model for Fish Diversion Studies at Wanapum Dam
Publication: Journal of Hydraulic Engineering
Volume 124, Issue 12
Abstract
A numerical flow model is developed for evaluating different fish bypass systems at the Wanapum Dam on the Columbia River, Wash. The model solves the three-dimensional, Reynolds-averaged Navier-Stokes equations combined with the k-ε turbulence equations. The governing equations are formulated in generalized curvilinear coordinates and the bed roughness is introduced through wall functions. The paper discusses the calibration of the numerical model and its application in the design of a bypass system at Wanapum Dam on the Columbia River, Wash. The numerical model is validated with data taken in a 1:16 scale hydraulic model of a powerhouse intake bay. The model is found to reproduce accurately all of the flow characteristics that are believed to be important for the evaluation of a fish diversion system.
