Because the traditional resources are getting less and less, lots of countries focus on new resources and the wind resource is favorite. Blades decide efficiency of wind turbine as the"heart"of energy transforming of wind turbine. High efficiency and power, special aerofoil for wind turbine and noise were focused on by the researchers. However the steps of wind turbine design were very complex and their sizes were very large, so it was very hard for high efficiency wind turbines design. In this paper, the traditional design methods and the fast developing CFD methods were combined, and a good designing system was set up by good computation soft——MATLAB. This had good meaning for shorting wind turbine design.Compared and analyzed Glaurt method with Wilson method considering the characteristics of wind turbine, a Wilson method design theory considering the tip loss was showed; the solving steps of Wilson method were analyzed; a programmer was written with MATLAB language .The complex problem of hand-design was avoided by this programmer, and it was very quick and useful using this programmer. And a three blades 10KW miniature wind turbine was design in this paper for some reference in the future research.Numerical simulation using FLUENT software based on solving 3d Reynolds average steady Navier-Stocks equations with SST K-ωturbulent model and mixing plane was used for the contact planes. Compared numerical results with the experiments Performance, the numerical error was in 5%, proving the validity of the calculation.The different inlet velocities impacting power factor were using to study the out performances of wind turbine. And the good running area was given by analyzing the numerical results and the characteristics of wind turbine. At the same time, the pressure coefficient distributing rule and blade stalling characteristics were shown.In the end, the directions and methods of profound research through the CFD analytical result and present state of wind turbine were pointed out.
