| Abstract: | Wind energy is a clean and renewable energy, and much attention is being attracted to the use of wind energy. In this paper, a 3D model of wall augmented wind turbine is established. Numerical simulation is carried out by using a computational fluid dynamics (CFD) software FLUENT. With the same upstream wind speed, the ratio of augmentation benefit of the wind turbine in different sizes and shapes of walls are calculated. Influence of the wall on the augmentation effect and its laws are acquired. The augmentation effects are then analyzed and optimized using the orthogonal method, and the rule of the augmentation effect of the wind walls obtained. The simulation study provides a reference for the experiment and construction of the wall augmented wind turbine. |
