    Abstract:   本研究利用FLUENT計算流力軟體來模擬小風車之流場,求解三維穩態不可壓縮的Navier-Stokes方程式。
      The aim of this study is using computational fluid dynamics software, FLUENT, to simulate the flow field of small wind turbines. FLUENT solves the three-dimensional, steady, incompressible Navier-Stokes equations.
      We first used the computer aided design software, PRO/ENGINEER, to draw the configurations of small four- and six-bladed wind turbines. We then used the grid generator, GAMBIT (provided by FLUENT) to generate grids. A point, line, surface, and body approach was used to generate unstructured grids for the wind turbines. The grids were then fed into FLUENT to solve for the flow fields. The numerical results were compared with the experimental data. The comparisons were plotted as the power coefficient against the tip speed ratio.
      The results of our study show that grid density and quality have decisive effects on the accuracy of the numerical solutions. We increased grid density on the surface of blades and the disk which enclosed the wind turbine. The calculated power coefficients agree well with experimental data for the four-bladed wind turbines. The discrepancies are larger for the six-bladed wind turbines but the trends are consistent. FLUENT can be an effective tool in designing small wind turbines.
