Abstract
The valley wind environment is an important part of the study of the street valley microclimate. The wind environment in the street valley has close relationship with the diffusion capacity of pollutants. Its advantages and disadvantages have a direct impact on the air quality in the street valley. The wind environment of the street valley is mainly affected by the geometrical features and flow directions of the valley. In this paper, the influence of the geometric features of the ideal street valley and the flow wind field on the wind environment in the street valley and the diffusion capacity of pollutants are analyzed by the method of computational fluid dynamics (CFD). The result show that vertically flowing down the wind, there is a clear air vortex in the street valley, which is not conducive to the spread of pollutants, and the air quality is poor.
