Numerical Analysis Of Wind Load Characteristics And Wind Vibration Response Of High-rise Buildings Integrated Vertical Axis Wind Turbines

As a new building form of energy conservation and emission reduction,wind turbine and building integration have a very positive significance in advocating green sustainable development and low carbon economy.To make full use of wind energy resources city,the development and design of new type wind power integration architecture is various,need to find effective ways to structure such as the ability to resist the wind and the wind load response analysis.The numerical method as a means of economic,high efficiency and low consumption can be used for simulating the overall structure of the architectural design after,so as to verify the structure of security and stability meets the design requirements.This article first uses the FLUENT software to load the vertical axis wind turbines integration of high-rise building wind load research,using ABAQUS software for the whole building model with the wind to the wind vibration response analysis,the main research content is as follows:(1)Under the condition of atmospheric boundary layer through a numerical simulation of the CAARC standard architectural full-size three-dimensional standard architectural model is established,under the condition of the same wind speed for two-thirds of h location point of wind pressure sampling,through the comparison with wind tunnel test data,verifying the UDF program to write,boundary conditions and set the rationality of the turbulence model,test and verify the reliability of three-dimensional numerical simulation method,which laid a foundation for the follow-up work of this paper.(2)The use of FLUENT software architecture for wind load of wind power in the overall analysis,based on the LES and structured grid turbulence model,set up two full-size three-dimensional grid model,namely no wind machine concave Angle of building model and a wind machine concave Angle building model.To calculate the building in the absence of wind turbine,wind turbine stationary and wind during three cases the stress characteristics of different wind speed,speed research building surface wind pressure distribution characteristics and the building of wind load characteristics.(3)The use of ABAQUS software wind vibration response analysis was carried out on the wind construction,set up after the installation of vertical shaft wind turbineof three dimensional calculation model,the fourth chapter wind load simulation results applied to model and modal analysis and the wind vibration response analysis,compare with load code for the rationality of the verification results.
