Abstract

In recent decades, several studies of hydraulic characteristics of spillway have been conducted. At the initial stage of design, hydraulic characteristics of spillway shall be investigated thoroughly either experimentally or numerically to provide better insight of flow behavior and predicting any critical area which can endanger the structure and the environment. The present paper focused on the numerical study of free surface flow over the three dimensional (3D) unsymmetrical smooth spillway. This paper aims to investigate hydraulic characteristics by using 3D numerical simulation in terms of water surface profiles, surface velocity profile and velocity profile at the downstream. The governing equation of Reynolds-averaged Navier-Stokes (RANS) equation is numerically solved using volume of fluid (VOF) method and Realizable ?-? (RKE) turbulence model. The numerical simulation successfully estimated hydraulic characteristics and show a good agreement in terms of profile pattern compared to establish papers.
