PHOENICS-based Simulation Study on Winter Wind Environment in Outdoor Space of Old Communities—Taking Sanlihe Community of Beijing as An Example

The quality of wind environment is closely related to the comfort of outdoor space, and the wind environment is an important factor affecting outdoor activities of urban residents in winter. Taking the old Sanlihe Community in Beijing as an example, this paper uses the PHOENICS simulation software to simulate the outdoor wind environment of the community in winter in a physical way, analyse problems existing in the outdoor environment in a more scientific way, and put forward optimization suggestions, so as to provide an objective basis for future practical transformation.
