Abstract

See full text

A high-efficiency airfoil for VAWT is shown to demonstrate an increased power coefficient of higher than 0.4 due to increased lift at lower angle of attacks (“AOA”). The high efficiency airfoil of the present invention includes a modification to the leading and trailing edges, resulting in an improved power coefficient at higher AOAs. For the leading-edge modification, a cylindrical nose was placed at the leading edge, and for the trailing edge a scorpion tail was added to the trailing edge with angles at 20 degrees in either positive (CCW) or negative (CW) direction. The results of these modifications were compared with the corresponding results for the baseline model to illustrate their impacts on the lift and drag coefficients.
