Combining with CFD wind field simulation of different architectural layouts, this paper studies the adaptive layout of residential architecture on surrounding environment.
Therefore, based on the Gaussian model, at the same time, combining with the CFD wind field simulation, this study provides a reference for the architectural layout planning in residential quarter.
Through the CFD simulation, it is known that when determinantal layout buildings are perpendicular to wind direction, buildings in upstream of airflow may prohibit the wind field of buildings in downstream, which furthest help the building to adapt to the requirements of wind-resistant in winter in residential area.
The pollutant concentration distribution of three kinds of layouts including determinantal layout, oblique column type and alternate layout can be known through CFD simulation.
