Researches about the aerodynamics of wind turbine with straight wing vertical axis(SW-VAWT)are very limited, in spite of a number of advantages such as low dependence on wind direction variation and easy constructible straight blades. For these reasons, we are researching the lift type SW-VAWT for many years. The elucidation of the behavior of the flow inside and neighborhood of the wind turbine during the rotation is very important because of the performance improvement of the vertical axis wind turbine. This research examined to the aerofoil characters by using the numerical simulation technique and the precision of the prediction technique was confirmed as this result. Furthermore, we estimated flow behavior during the wind turbine rotation by using this numerical simulation technique, and evaluated the flow around the wind turbine. This paper presents outline and results of these calculations and evaluations.
