An inverse design process is applied to determine blade
shapes used in vertical axis wind turbines (VAWTs). The
method is based on the modified Garabedian-McFadden
technique that uses the deviation of the pressure distribution
or the velocity distribution on the surface from a target
pressure or velocity distribution, and modifies the blade
surface in order to reduce this deviation. The method was
originally developed for wing design and applied for such
aerofoil shapes as those of horizontal axis wind turbine
blades. The procedure is employed here successfully to find
a target shape that is used in a VAWT operating with bladesof constant thickness rather than of aerofoil shape. The method is presently applicable to determine blade shapes in a two-dimensional section, and considers someperformance criteria of VAWTs; thus, it contributes to finding
blade shapes that most closely corresponds to the efficientoperation of such turbines.
