Abstract: Architectural wind environment study is a cross discipline between aerodynamics and atmospheric science focusing on the interaction of architectures with the urban wind fields. In the study, wind tunnel tests and flow visualization approaches, as consistently used in aerodynamics, are applied for the investigation of the wind field distribution and variation in urban atmospheric boundary layers and around the architectures. The numerical computations and wind tunnel tests are mutually complementary and their combination can improve the experimental studies. In the present paper, the wind environment of Beijing Central Business District (CBD) is studied. The simulation of the urban atmospheric boundary layer in the wind tunnel and the method of the wind field visualization around architectures are described in detail. The experimental results are compared with numerical computations and they are in agreement. Some useful suggestions in the study are made for the improvement of urban planning and urban wind environment in CBD area.
