dc.description.abstract | This study investigates the influence of free surface variation on the velocity field using numerical simulations of flow around a sharp-nosed pier that is representative of a typical masonry bridge pier. This study evaluates the assumption that free surface effects are negligible at small Froude numbers by comparing the change in flow field predictions due to the use of a free surface model (i.e. multi-phase simulation with a Volume of Fluid (VOF) model in place of a rigid-lid approximation (i.e. single phase simulation). Results show that simulations using the VOF model are in better agreement with experimental data than those using the rigid-lid approximation. Importantly, results show that even though the change in free surface height near the pier is small comparative to the approach flow, it still has a significant effect on velocities in front of the pier and in the wake region, and that too at low Froude numbers. | en_GB |
