Numerical Modeling of Hydrodynamic Performance on Porous Slope Type Floating Breakwater

A breakwater is a coastal building that aims to break up or withstand wave energy enters the beach so characteristics of incoming waves are by calculations and can reduce abrasion on shoreline. Designing floating very complicated because it depends many aspects. These fundamental aspects depend each other, if one these changes, integrity structure will also change. One magnitude transmission reflection coefficients generated breakwater. This research study hydrodynamic performance due variations in slope porosity reducing reflecting with computational fluid dynamics (CFD). The slope-porous dimension based previous experimental data, including constant water depth 0.75 m, height 0.05 - 0.125 period 1.1 2 sec regular waves. results numerical model validation experiments all quite good, which less than 10% for both reflection. Analysis influence changes mooring line angle, simulation carried out at an angle 30 deg 90 produces average coefficient 0.79 0.21. While effect level elevation (0.85 0.65 m) gives reasonably significant 0.85 0.13. be gentler high tide, higher. However, loosen low causing move more freely eliminating function itself tidal phenomenon becomes challenge experts designing structures produce effective efficient performance.
