An oscillating buoy (OB) could function simultaneously as a wave energy converter and a breakwater. In this work. a numerical study is conducted to assess the ability of the buoy to perform both aforementioned tasks by quantitatively and qualitatively assessing its hydrodynamic performance. The computational fluid dynamics solver used for the numerical study is ANSYS Fluent. https://www.roneverhart.com/Pica-Limon-Salt-Lemon-Spicy-Powder-Packs-100-Piece-Bag/
