Visual Simulation of Building Wind Environment Based on Computational Fluid Dynamics

Abstract

Wind environment visualization research is of great significance to building energy conservation. In this paper, the wind environment simulation of the building group is carried out by CFD software. The wind environment status of the building group is determined by the assumptions and analysis of the wind speed, building group layout, building height, and ground roughness in summer and winter. The results show that under the typical wind speed and wind direction in summer, the wind environment of the project is good, and there is basically no vortex or windless area of the site. About 70% of the open window can be opened. Under the typical wind speed and wind direction in winter, the wind speed of the pedestrian area is within 3m/s. Except for the first row of buildings, the wind pressure difference between the windward and leeward surfaces is basically between 1 and 6Pa.
