Overview

Breakwaters are widely used to provide economical protection from waves in harbors and marinas. Also, the submerged breakwaters were extensively adopted to reduce wave motion in front of vertical wall breakwaters. In this study, the flow pattern is numerically simulated using FLOW-3D software. To model the flow field turbulence, the standard and RNG turbulence models are used. According the numerical results, the standard turbulence model had more accuracy than RNG turbulence model. Also, the Volume of Fluid is applied for modeling the variations of flow free surface. To validate the numerical results, Li and Fleming (2001) study results are used. According to numerical simulation results, the numerical model predicted the variation of free surface with reasonable accuracy. For example, the MAPE is computed 11.808% for numerical model. Also, the variations of other hydraulic and hydrodynamic parameters were examined. For instance, the maximum flow field pressure before and after break were calculated 4763 and 4923 pa, respectively.
