Abstract / Description of output

A new kind of perforated free surface semicircular naval structure is presented. The hydrodynamic characteristics of naval structure are investigated in regular and irregular wave conditions under the different water depths, submergence depths, wave heights and wave periods. The performance of the naval structure was evaluated in the form of transmission coefficient (C_t), reflection coefficient (C_r) and energy dissipation coefficient (C_l). It is found that the wave attenuation ability of the naval structure model improves with the increase of submerged depth and relative plate width. The naval structure performs better as an energy dissipater than as a wave reflector, and is suitable for offshore infrastructure construction.
