With the development of computational fluid dynamics (CFD) technology, the design can not only predict indoor airflow analysis and evaluation of various parameters, which can be selected both to protect the process needs to meet human comfort, and can create a good indoor air distribution in the form of air quality and energy conservation, and the buildings outdoor airflow simulation the buildings outdoor thereby affecting the flow field and the building layout planning to achieve the best flow distribution needs. The high-rise building is a special building groups, especially for tall buildings buildings, there is mutual influence and more complex flow field flow around effect, relative to the flow field of outdoor, architectural outdoor wind field related to effective diffusion of the height at pedestrian safety, outdoor pollutants, outside the building glass curtain wall design, therefore it is necessary to attach importance to study. Firstly, the characteristics of high-rise building outdoor flow field, using the commercial software Fluent simplified model based on the use of standard k? Ε model, analysis of the flow field of high-rise building outdoor air flow phenomena as well as its velocity field, pressure field distribution The study adjacent building between wind environmental impact parameters, building height, spacing and width of the high-rise building outdoor wind environment, and to provide guidance for further scientific research and engineering design. Also describes the principles and techniques of CFD technology to achieve the form, select the appropriate mathematical model, meshing way, iterative methods, convergence criteria provides a theoretical support for a specific physical model. Secondly, we also studied the plane layout for building wind environment around than in wind speed than the assessment under standard system, the line at the height of the wind speed and wind vector analysis compared the pros and cons of building layout, draw wind speed than the evaluation system under the best choice for outdoor wind environment. Finally, on a practical adjacent building outdoor wind tunnel test results of the flow field numerical simulation and comparative analysis with, verify the practicality and reliability of the numerical simulation method, while adjacent buildings on the high-rise building outdoor wind farm the impact of the wind pressure distribution design basis for the design of a similar architectural glass curtain wall. The results of the numerical simulation of a certain theory reference and basis for urban planning and high-rise buildings designed. CFD numerical simulation studies and comparative analysis of wind tunnel test instance, to show the powerful effect in the actual design and development of CFD technology. Therefore, our research workers should CFD technology role before the move to the design phase, more effort can be applied to study up.
