英文摘要： More and more attentions are focused on the wind energy all over the world. Wind power generation is an important strategy to deploy renewable energy in China. The wind energy is abundant in super tall building environments. Open holes set up at a proper height of the super tall building may be used to utilize the wind energy effectively, and can reduce the overall wind loads on buildings. Although there is an actual project which applied the wind power generation to the super tall buildings successfully and received widely acclaim, research work related to similar buildings are still not enough. By means of wind tunnel testing, numerical simulation and field measurement, the proposed project aims to investigate the wind speed amplifications and flow field characteristics in the open holes of super tall buildings with openings, reveal wind energy collecting principle and wind energy distribution in the open holes of such buildings. Mathematical models for calculating wind speed amplifications and wind energy in the open holes will be proposed in order to provide theoretical foundation for wind power generation. Wind load characteristics and wind-induced response principles during the running process of the wind turbines will also be investigated, and the mathematical models of wind loads on super tall building will be proposed for wind-resistant design of such buildings. The distribution of aerodynamic noise inside and near the open holes caused by the running of wind turbine will be studied. The results can be used to evaluate the influence of wind power generation on the building serviceability. Furthermore, improvement and optimization measures will be proposed. The research achievements obtained from this project are expected to provide some scientific information for wind power generation and promote the application of wind power generation in super tall buildings.
