A RESEARCH ON SPATIAL CHARACTERISTICS OF BUILDING WIND ENVIRONMENT
Yang Li
ABSTRACT/ Taking Tongji union square buildings as the research subject and according to Shanghai’s typical climate environment, this paper
elaborates the geometric modeling, the definition of calculation catchment area, the grid division, the selection of boundary conditions and turbulence
models in the modeling process of numerical simulation of wind environment by using the Fluent software as the research tool. And it carries out a
simulating research on the different temperature, wind pressure, and wind velocity of different cross sections and longitudinal sections of Tongji union
square buildings in different seasons, which reveals the general laws of building micro-climate environment and building spatial structure and which
provides a useful reference for the application of numerical simulation method in real projects afterwards.
KEY WORDS/ wind environment, CFD technology, environment simulation
