Computational hydrodynamics of an offshore intake well with curtain wall

The wave-structure interaction of an offshore intake well with a curtain wall is computationally investigated with regular waves. The simulation is done using ANSYS-FLUENT, Computational Fluid Dynamics (CFD) tool. The computational domain is governed by continuity and the Reynolds Averaged Navier-Stokes (RANS) equations and modeled in a Cartesian grid system. The combination of structured and unstructured mesh is used to discretize the simulation domain. The numerical model is developed based on the pressure-based transient solver, and the Volume of Fluid (VOF) technique is selected to trace the free surface elevation. The simulations are performed using the 1:20 scale model by varying wave period (T) and wave steepness (H/L). The run-up on the seaward face and pressure on both sides of the curtain wall are measured. The numerical run-up shows good agreement with the experiments for the d/L range of 0.15 to 0.36. The pressure on both sides decreases with increased d/L values and follows the same trend as experiments.
