Research On Building Shape Reconstruction Method Based On CFD Wind Environment Simulation And Comfort Evaluation

With the continuous advancement of urbanization and the continuous integration of large urban areas,a series of active and passive issues have also emerged.Crowded urban population,excessive resource consumption causing traffic congestion,waste of land resources,and urban heat island effects,etc.At the same time,people have higher and higher requirements for living and working environment.How to improve the efficiency of land use in the process of urbanization and give full play to regional advantages and characteristics to create comfortable living and working environment has become a hot research direction.The study applied the CFD numerical simulation technology to the architectural wind environment simulation in the early stages of architectural design to guide the optimization of architectural design solutions through literature research and theoretical method research,and explored the role of CFD technology in architectural design.The whole framework progresses layer by layer in four stages.First of all,I conducted a detailed survey of the current domestic CFD technology-related research on building design and wind environment simulation to master the current cutting-edge research,related technical methods,and establish a research framework and method based on my own subject and implement its methods,modeling techniques,fluids Learning by software operations such as meshing technology.Secondly,the theoretical knowledge in the research is combed,including the characteristics of wind,architectural design ideas,the characteristics of wind flow after encountering the building,and the theoretical basis of numerical calculation,etc.,for the reliability analysis of the simulation results mentioned in the following research Foreshadowing the theoretical basis.Next,based on the relevant domestic norms and standards,establish wind speed,wind pressure,temperature,air age and other architectural design wind environment evaluation indicators combined with architectural design ideas to build a wind environment evaluation system from space utilization and functional redundancy,and Combine human body comfort model theory to construct human body thermal comfort model and optimize building design scheme.Finally,taking the example of a single-education public building in Shenzhen area as an example,combined with the CFD numerical simulation technology,the above-mentioned research methods and ideas are applied to it,and the simulation analysis is carried out on the typical working conditions in winter and summer.From the design of the wind environment guidance plan to the indoor wind environment guidance function and the design of the window,the progress is based on the establishment of the evaluation system,and the thinking is constantly optimized and refined.This paper takes the building wind environment as the starting point,and integrates the evaluation indicators of various building design wind environments with the architectural design ideas to build a design evaluation system.Taking CFD numerical simulation technology as the link,the human comfort goal combines the outdoor outdoor design of the building to achieve a complete architectural design evaluation and optimization system with multiple angles and clear levels,providing a new architectural design idea.
