Study on Hydrodynamics of a New Comb-type Floating Breakwater Fixed on the Water Surface

Through the physical model cross-section experiment, the effects of the relative width and groove depth on the transmission coefficient, horizontal wave force and vertical wave force of the new comb-type floating breakwater (FBW) model under fixed condition are observed. The results show that the hydrodynamic parameters of the new comb-type FBW are mainly influenced by its relative width under the action of regular wave, and the transmission coefficient decreases with the increase of its relative width. Especially when the relative width is 0.139 to 0.188, the transmission coefficient of the new comb-type FBW decreases rapidly with the increase of the relative width, and the horizontal wave force and the vertical wave force change slowly. This indicates that the new comb-type FBW has obvious effect on wave dissipation about short and medium waves. In addition, numerical investigations of selected experiment cases are conducted using RANS based commercial CFD code Flow3D. The numerical results show a good ability to capture the hydrodynamic interaction effect of the fixed FBW.
