Abstract

A method to design aerofoils is discussed in order to improve aerodynamic efficiency by removing discontinuities in the curvature and slope of curvature. It is shown to delay stall and flow separation for two low Re-number aerofoils (NACA0012 and E387). Laminar boundary layer tonal noise is shown to be suppressed. Aerodynamic and aeroacoustic performance of the blades used for kinetic turbines is also discussed. Computational and experimental results are analysed.
