The major advantages of using floating breakwater in comparison to conventional fixed<br />ones are lower cost of construction, using in severe hydrodynamic conditions and high speed<br />installation. Therefore, engineers lead to design and use floating breakwaters in those situation in<br />which this type of breakwater is more suitable to construct. To predict floating breakwater behavior, it<br />is essential to investigate flow characteristics in the vicinity of structure. In this regard, numerical<br />modeling is presented based on the solutions of 2DV Reynolds Averaged Navier-Stokes (RANS)<br />equations and the VOF method using in Fluent Software.<br />To generate wave, a sub-model has been developed and hooked to the main software. Results obtained<br />from the numerical model then validated by experimental data cited in the literature to represent the<br />capability of model in simulation of complicated problems. Numerical modeling shows that the single<br />fixed FB operates well but, the attached plate in the front part of the FB significantly enhances the<br />efficiency of the structure and with regard to cost-effectiveness, the configuration of the FB with the<br />attached plate should be considered for design purposes. Also, double FBs and trapezoidal ones with<br />inclined faces of different angles are simulated. It is found that the trapezoidal FBs are the most<br />efficient in comparison to the other types of FBs. https://jhyd.iha.ir/article_85506_e01424d29df5d592322f8bf1881cc31d.pdf
