Diffraction waves on general two-legged rectangular floating breakwaters

In this paper, hydrodynamic characteristics of general two-dimensional rectangular floating breakwaters (FBs) with two legs in water finite depth and infinite domain subjected to sinusoidal waves are studied using a numerical panel method. A parametric study is carried out order quantify the effect leg size angle on diffraction problem, especially transmission reflection coefficients. Results show that play an effective role breakwater’s response incident two-legged FBs could be used for achieving higher efficiencies compared conventional FBs. The parameter shows inverse T-type FB best Π type least good terms However, practical considerations might also considered when choosing configuration different applications. • Hydrodynamic analysis breakwaters. method has been used. Transmission coefficients derived angles. Diffraction wave formation induces hump vertical exciting force. Maximum amplitude converges particular value which corresponds zero coefficient.
