A Preliminary Study of Breaking Waves Phenomenon on a Numerical Wave Tank

The detailed prediction of breaking waves transformation may be a main concern within the ocean structures design and development at the top of submerged flat reefs. In this preliminary analysis, phenomenon of solitary wave on the reef can be simply interpreted in two-dimensional numerical wave tank (NWT), based on the computational fluid dynamics (CFD). A more sophisticated method, large eddy simulation (LES) turbulence model together with volume of fluid (VOF) for capturing free-surface, could clarify two-phase incompressible flow Navier-Stoke equations by finite volume approach. The other approaches have been used. Existing model results, wave generation, breaking wave, and velocity distributions, devised the validity of laboratory measurements. This set of tests desired to examine the effect of different reef configurations (reef length, reef height, incident wave height, and manning coefficient) on the solitary wave propagation. Results show that the model can contribute decent predictions of the phenomenon of breaking waves on various submerged flat reef configurations.
