국문 초록

This study assumed artificial seaweed mats as porous media in a computational fluid dynamics model and examined the changes in flow velocity and bottom shear stress under various installation conditions of the mats. To consider the pressure dissipation effect of the mats, the flow reduction reproduction method proposed by Brito et al. (2016) for artificial vegetation was applied to the Fluent model. The changes in flow velocity due to the scale and arrangement of the seaweed mats were analyzed when installing the mats around the mono-pile structure. Through the numerical results, it was confirmed that by adjusting the density and height of the artificial seaweed mats, it is possible to regulate the flow velocity and shear stress occurring in both the internal and external zones of the mats. In the design of the artificial seaweed mats, it was confirmed that by configuring the outer mat height to gradually increase and placing high-density mats furthest from the pile, while positioning relatively low-density mats closer to the inner side of the pile, reductions in flow velocity and shear stress at the base of the mono-pile can be achieved, along with mitigation of scouring effects.
