Abstract
In recent years, there has been growing concern about the depletion of finite energy resources such as fossil fuels, so renewable energy has become an important research area. In this study, using wind power generation as the renewable energy technology, we executed analysis for the air flow and fluid power around a downwind windmill using CFD. A downwind windmill can generate power under strong wind conditions, so it can generate stable power in Japan. In addition, we propose and perform an educational method for mechanical design support by CAE/CFD.
