Resumen

In this paper, three-dimensional numerical analysis of flow field patterns in an open channel bend influenced by a weir and a sluice gate is presented. The simulation was performed using the open source computational fluid dynamics (CFD) solver based on finite volume method (FVM) – OpenFOAM. Turbulence is treated using Reynolds-Averaged Navier Stokes equations (RANS) approach (i.e., k–ε, k–ω, y k–ε(RNG)), and the volume of fluid (VOF) method is used to simulate the air-water interface. The numerical results are assessed against experimental data (water depth) at different points within the domain. Water depths were measured by means of water level sensors and limnimeters. Therefore, the three-dimensional numerical results obtained are used to analyze streamlines, components of velocities, and secondary flows.
