Abstract
Concerning wave energy dissipations caused by flow separations and resultant vortex formations from sharp edges of an angular body, a twodimensional analysis on wave transformations and wave forces on an angular body has been developed. In the analysis, a damping wave model was newly proposed to account for the wave energy dissipation approximately. An equivalent linear damping coefficient of fluid and a spatial range of the damping fluid are necessary in the analysis. In order to figure out these factors, wave tank tests were carried out. Two different structural models, i.e., a curtain-walled breakwater and a semi-submerged rectangular body, were used in the experiment. It was confirmed that the numerical analysis developed here is useful for estimating wave transformations and wave forces about an angular body including the effects of wave energy dissipation due to vortex formations around the body.
