Research on the Influence of Building Layout Forms on Wind Environment in Urumqi City Based on CFD Simulation

This paper selects 15 typical layout forms of 3 types of residential clusters in Urumqi City, combines the climate characteristics of Urumqi City, and uses the numerical simulation research method of CFD model to explore the influence of different building layout forms on the wind speed of residential areas in winter and summer, and the wind pressure before and after buildings, and distribution of air vortices. Under the comprehensive consideration of ventilation in summer, windproof in winter and comfortable outdoor conditions, the layout form of building groups most suitable for Urumqi climate conditions was put forward, and suggestions for optimizing the outdoor wind environment of existing buildings were put forward to improve the micro-climate environment to achieve the purpose of energy saving.
