In this study, the offshore wind turbine of blade airfoil is studied and designed to obtain the highest output power under specific atmospheric conditions. The problems of the optimum shape of the blade are complex with the mathematical description of aerodynamic load and some constraints with the object. This study aims to develop two types of airfoil model by directing the designed method and a mathematical model for fluid dynamics. The blade element of momentum theory nor the mathematical model was implemented and improved on the blade airfoil. As a result, a high-efficiency airfoil model was designed through CFD simulation and verified by comparison with experimental data.
