Iterative boundary element method for modeling an inverted T-type porous barrier in presence of ocean currents

Abstract

The present study investigates the scattering of ocean wave and currents by an inverted T-type lightweight surface-piercing wave barrier that is situated over a uniform sea bed. To handle the boundary value problem (BVP), an iterative boundary element method (BEM) has been used. To analyze the efficacy of employing thin wave barriers, the impact of porosity, relative submergence depth and width of the barrier on the hydrodynamic properties (like wave force, reflection, dissipation, and transmission) are investigated in the presence of ocean currents. The simulated outcomes demonstrate that the Doppler Shift effect of the frequency due to the presence of ocean currents significantly influences the behaviour of the aforementioned hydrodynamic properties. Moreover, these simulated results also demonstrate that the use of lightweight wave barriers provides a better wave energy dissipation compared to the bulky submerged structures.
