摘要 | Three-dimensional unsteady Reynolds averaged incompressire. Navier-Stokes equations are used to simulate the aerodynamic flows in a horizontal axis wind turbine. The numerical method that adopted in this paper is proved to be effective to predict horizontal axis wind turbine aerodynamic characteristics by contrasting the numerical results to the wind turbine experimental data of the power coefficient. The pressure distribution contours of the blade surface, of different positions perpendclar to wind turbine axis, and of a meridional plane through the rotor axis are obtained too. At last, the contours of axial-velocity vector and radial-velocity vector at those slices are also gained. From those figures, analysis of the flow field is performed. Such as the flow separation characteristics, the wake structure and the course of the wake generation, expension, development, shrinkage and collapse. |
