Numerical Simulation of Backwater at Bridge Piers (Technical Note)

Flow pattern around bridge pier and its effects is one of the interest of hydraulic engineers. Since numerical models are progressing as a tool to analyses flow fields, in this paper numerical simulation of flow pattern around bridge pier is studied and its consequent effects on backwater is investigated. Fluent model (version 6) is used and water surface is simulated using volume of fraction (VOF) method. Comparison of numerical and experimental results show good agreement.
