The laminar boundary layer on a rotating wind turbine blade

摘要

The present paper describes a method to calculate velocity profiles in the boundary layer ofrotating blade. A differential approach is used to solve the laminar boundary layer equations. Theeffects of tip speed ratio, dimensionless radial position r/R and angle of attack have been analyzed.The test airfoils used in the simulations are NACA 63-215 and S809. The resulting velocity profiles inthe chordwise and spanwise directions are mapped and stored in a Database according to theboundary layer parameters.
