Transient Waves and Beaches
The flow properties around coastal structures must be considered and acknowledged within the design process.
In this study, the structure of separation vortices formed behind structures was observed. Additionally, the flow condition behind the structure was reproduced through the numerical model, OpenFOAM. The flow velocity field was roughly in agreement with the experimental results, though the water level and wave force were overestimated by the numerical model. The authors believe that improvement of the free-surface capture method is necessary to improve calculation accuracy.
