The lay outs in this thesis is based on basic theories and the test the performance of the product by wind tunnel test and vehicle test. Furthermore, in order to find out the effect of structure change on hub which is one of the components of wind turbine, I compared the actual performance between the existing model and the modified model thoroughly. To improve the performance of wind turbine, I modify the structure of the hub and analysing base model and modify model by using Star-CCM+. As a result, I found out the wing-shaped hub used model stablizes the spin in shorter time than existing model. Therefore, with the optimal blade selection, the structure modification on hub is a considerable variable on wind turbine design which is aiming better performance.
