Experimental and Numerical Efficiency Analysis of Absorbing-Type Vertical Breakwater

To evaluate the effectiveness of an absorbing-type vertical breakwater, a combination of laboratory and numerical simulations was conducted. Initially, the study focused on experimental tests involving both regular and irregular waves at two distinct water level. The numerical simulations, which specifically addressed regular wave conditions, were carried out using the OpenFOAM® C++ libraries. These simulations utilized the Reynolds-Averaged Navier Stokes (RANS) equations paired with the k-ω SST turbulence model and employed the Volume of Fluid (VOF) method to monitor the free surface behavior. The results from these numerical simulations corresponded well with the experimental observations, thereby validating the numerical approach. This validated methodology was subsequently applied to simulate a wider range of natural wave conditions, proving to be an effective tool for evaluating the performance on an absorbing-type vertical breakwater.
