Pressures acting on the airfoil surface are measured by a multiport pressure device. The test is carried out in a low-speed wind tunnel at Re 2.62×10 5. This chapter then discusses ways to establish a data set for blade design and concludes with a view on future research in the field of wind turbine blade airfoils. This paper presents the effect of wind tunnel sidewalls on the wind turbine airfoils with experimental and numerical methods. A number of methods for correcting characteristics for the effect of three-dimensional flow on the blade are presented. After a description of how airfoils can be tested, this chapter discusses methods to represent airfoil characteristics at high angles of attack. This chapter then discusses the requirements for wind turbine blade airfoils and the effect of leading edge roughness and Reynolds number. The use of panel codes such as XFOIL and RFOIL and CFD codes for the prediction of airfoil characteristics is briefly described. This chapter then discusses ways to establish a data set for blade design and concludes with a view on future research in the field of wind turbine blade airfoils.ĪB - This chapter focuses on airfoils for wind turbine blades and their characteristics.
